Basic knowledge of the face - proportions, features and perspectives. When you paint your face, you are no longer confused~

â–²What will you create?


We have to explore the human body carefully, and now we are looking at the details on the face. The first thing the eye looks for in any environment is the human face. This also applies to art: the audience will first look at your character. Therefore, mastering expressions, especially the lively expressions of paintings, is very worthwhile.

In this article, Xiaobian brings the basics of learning facials - proportions, features and perspectives.


1. The proportion of the face

The skull is a slightly flat sphere with the jaw attached to the sphere, so the face is like an egg with a sharp side facing down. Two vertical midlines cut the eggs into three quarters. Place:

â–ª Mark the midpoint of the left and right halves: The eyes sit on the midline, at these midpoints.

â–ª Divide the lower half into one-fifth: the bottom of the nose is two points from the midline. The slit of the mouth is three points from the midline and only a little from the nose.

â–ª Divide the top half into a quarter: the hairline (not back) is two to three points from the midline. The ear is located between the upper eyelid and the tip of the nose, but only appears when the face is level. Raise or down to change the apparent position of the ear (see shortening).



Be aware that the width of the face is usually less than five eyes. The distance between the eyes is equal to one eye. It's not uncommon for people's eyes to be apart or closer together, but we noticed them (separate eyes give a childlike innocent impression, while tight eyes inspire for some reason). The distance between the lower lip and the chin is also the length of one eye.

Another way to measure is when the index finger is beyond the length of the thumb. In the image below, all distances marked are equal to this length: the height of the ear, the hair of the eyebrows, the nose, the nose to the chin and the pupil to the pupil.




â–· View information:

Viewed from the side, the head still looks like an egg, but points to a corner. The center line now divides the head into front (face) and back (skull).


On the skull:
â–ª The ear is behind the midline. In size and vertical positioning, it is still suitable for the upper eyelid and the bottom of the nose.

â–ª The depth of the skull varies between the two dashed lines shown in step 4.

on the face:

â–ª Place the same way as above.

â–ª The hollow portion of the base of the nose coincides with or slightly above the midline.

â–ª The most prominent point in the brow is 1 point from the midline.



2. Features

Rubbing eyes and eyebrows

The eyes are just two arcs that form the shape of an almond. There are no special rules here, because the shape of the eye can vary greatly with different emotions.

But we can notice the following trends:

â–ª The outer corner of the eye can be higher than the inside, but not the opposite.

â–ª If the eye is compared to the almond, the rounded portion will face the inner corner and the taper portion will be at the outer corner.



Eye details:

â–ª When resting, the iris is partially hidden behind the upper cover. If you look down, or if the eye is narrowed so that the lower cover rises, it only intersects the lower cover.

â–ª The eyelashes are swept outward and the lower cover is shorter (actually, most of the time does not need to be painted).

â–ª Whether the small oval shape of the tear duct showing the inner corner and the thickness of the lower lid are determined by the individual, depending on the person's style, because too much detail does not necessarily look good; the details should be reduced with the scale of the drawing.

â–ª The same situation with the folding of the eyelids, which in addition helps to express and can make the eyes look less alert. I found that when the drawing is too stylized, or so small, the fold can't contain without changing the expression, and it's best to omit it.

In the outline, the eyes are in the shape of an arrow (different concave or convex sides), and the upper eyelid may be a little bit or lower. In real life, you won't see the iris from the side, you will only see white eyes. When I did this at work, I received a lot of comments from readers saying "This is really weird" and I had to start to include at least some irises.


As for the eyebrows, the easiest way is to let it follow the curve of the upper eyelid. Most of the eyebrows are oriented towards the inside and the outer tail is slightly or much shorter.

In the outline, it completely changes the shape and becomes a comma. The comma seems to be a continuation of the eyelashes, then curls back into your eyes and eyes - in fact it sometimes looks connected to the eyelashes, you can also draw a curve, the upper thread of the eyeliner curls into an eyebrow.


nose

The nose is generally wedge-shaped, and the details of this shape are easier to visualize and draw in 3D.

The sides of the bridge and bridge of the nose are flat surfaces, which may only imply the final drawing, although it is important to place them in the sketch of the building block so that the detailed part of the nose is placed and sized correctly. This is the flat side of the bottom of our wedge, connecting the wings and the truncated triangle of the tip of the nose. The wings are drawn inwardly into the septum to form the nostrils - in the bottom view below, it is noted that the lines forming the sides of the septum start from the front, not from the beginning. When viewed from the front, the diaphragm protrudes below the nose, which also means that in the 3/4 view, the other parts of the nostrils are hidden to varying degrees.



The trickiest part of the nose may be deciding what line to draw or omitting a good looking result! You don't always want the nose to be completely drawn because they are on the side. Similarly, the front nose here shows all four lines of the bridge and the connecting surface, but in most cases, if you only draw the next part, the wings/nostrils/separators (with your fingers) are even better. However, if the nose is a 3/4 view, drawing a farther line is almost indispensable. To achieve my own "exclusive nose" requires a lot of observation and trial and error, and like any subtle feature, I find it very useful to look at the artist's work, closely observe their noses and see what decisions they have made themselves.

Lips

Note on the lips:

â–ª The slit of the mouth should be pulled first because it is the longest and darkest of the three slightly parallel lines that form the mouth. It is not a simple curve, but a series of subtle curves.

â–ª In the image below, you can see an exaggerated example: Notice how they reflect the lines of the upper lip. They can be softened in a number of ways, and the central droop can be very narrow, because a sharp appearance, or such a widespread presence, is attenuated. But when the lower lip is fleshy it can even reverse and produce a slight, natural flaw. If achieving symmetry on this line is challenging, try to draw a method from the center and then go back and do the other side.

â–ª The two peaks of the upper lip are more pronounced, but they can similarly soften into a broad curve or even soften, making them fuse into a "topless" lip.

â–ª On the other hand, the lower lip is always a smooth curve, but it can range from almost flat to round. Marking the lower lip is always good, even if it's just a hit.

â–ª The upper lip is almost always thinner than the underside and protrudes less than the bottom from the face. If it is outlined, it should always be finer than the following, because the outline of the lower lip is emphasized by its shadow (skinny like it!)

â–ª From the side, the lips are in the shape of an arrow and the protrusion of the upper lip becomes clearly visible. The same is true for the contrast between the contours of the two lips: the flatter and diagonal are higher, and the lower ones are lower.

â–ª The slit of the lip is inclined downward from the side. Even if this person is smiling, it will tilt (or curve) and then rise to the corner again. Never tilt your mouth up and down.


ear

The most important part of the ear is the high C shape of its outer contour and the inverted U inside it, which marks the edge of the upper ear. Usually there is a smaller U (feeling with your fingers) above the earlobe, connected to a smaller C. The general effect is concentric around the ear holes (not a rule visible) and varies greatly. This may be stylized - for example, my universal ear, below, looks a bit like a stretch symbol.

When looking at the face from the front, the ears are sideways:

â–ª The inverted U-ring described earlier is now a separate unit. When you look at a plate from the side, you suddenly see its bottom inside.

â–ª The earlobe looks almost like a whole, more like an ear.

â–ª From this perspective, how thin the ear is depends on how far it is from the head and that it varies. However, it always leans forward slightly because this is the direction we evolved to listen.

From the back, the ear appears to be separated from the head: the funnel is used to connect the edges of the head. Don't be afraid of the size of the funnel, it needs to tilt your ears forward! This angle is more important than the edge.


perspective

Basically a ball with facial features drawn on the contour and the head can be shortened at different angles. It is very important to look at it from all angles of real life in order to be familiar with the way these features stand out and sink, sometimes overlapping each other in unexpected ways. The nose protrudes, but the forehead, the humerus, the central part of the mouth and the chin do so, while the mouth and the eye socket are sunken against the surface of our ball.

When we draw the face on it, we reduce it to a flat 2D surface where the reference line is straight. For any other angle, we need to shift our thinking to 3D and realize that the egg shape is actually like an egg, and the lines we used previously to locate the characteristic curves around it, such as the equator and the latitude of the earth: when the eggs When tilted, their circularity is expressed.
Then, placing the feature is just a matter of drawing a cross centerline at the desired angle. Then we can slice the top and bottom half as before, and slice the eggs, remembering that the slice closest to us looks thicker. This process is the same as drawing a face looking down or up.

â–·Look down. All the characteristic curves rise and the ears move up.

â–ª Because the nose is protruding, it is beyond its line (see photo) and the top looks closer to the mouth - if the head is low enough, the nose will just overlap the mouth. From this point of view, the nose does not show details at all, just a little nose.

â–ª The curve of the eyebrows is flat, although it requires extreme viewing angles, making them curve in another way.

â–ª In the eye, the upper eyelid becomes more prominent and quickly changes its usual curve to cover the sphere's sphere.

â–ª The upper lip almost disappears and the lower lip appears larger.

â–ª It's important to note that because the mouth follows a general curve, it looks like a smile, so you may need to adjust the reality to paint.


Look up:


â–ª All the characteristic curves are down and the ears move down accordingly.

â–ª The upper lip shows its surface and usually does not face the viewer. The mouth will be like a grin!

â–ª The eyebrows increase the curve, but the lower eyelid curve decreases, causing an eye-opening effect.

â–ª The bottom of the nose is clearly displayed

Look at the side

â–ª When a person is almost from the back, all visible is the forehead and cheekbone points. The line of the neck overlaps with the chin because it points to the ear. When the face is rotated, the eyelashes will appear again in the field of view.

â–ª Then some of the eyebrows appear and the tip of the lower eyelids appears behind the curved cheeks.

â–ª On the near side, the eyeball and lips appear (but the gap in the mouth is still small), and the line of the neck merges with the line of the chin. You can still see a part of the cheek that hides the nostrils.
