PORTRAIT PREP SERIES: Lesson 2 The Skull, Muscle and Skin

PPC-Lesson2.0.jpg

 

Welcome back to Portrait Prep! (If you missed the previous lessons, you can find them here and here: IntroLesson 1, Lesson 1.2).

 

In this section, we're going to talk about the skull, the facial muscles, and the skin. These parts work together to form what we see as a complete face, so it’s important to get to know what’s going on under the surface to know how each part affects what we see.

The Skull

If you're using graphite and you're new to drawing the skull, remember to be patient with yourself and take it slow. Think more about the proportions of each of the areas you're drawing.

I typically start any drawing in the top left corner, move downward through the drawing, and end at the bottom of my subject and over to the right. I'm right-handed and I don't want to impair my ability to see what I've already drawn or smudge anything, so this method is effective for me.

To begin, draw a curve on the top right side to represent the major side plane of the skull in the cranium area. Next, make the same identical mark on the left side.

Once you have those two marks down pretty accurately, connect them at the top by another curved line which will serve as the top of the head.

The rest of the skull should be proportionate to the top part of the head.  Ultimately there is no right or wrong way to draw the skull, but everything needs to be relative in proportion to what you've drawn prior to your current marks.  If you find that your proportions are becoming out of scale to the rest of the drawing, simply erase and start that portion over.  (I’d like you to attempt to draw it just by eyeballing the proportions for now. In a later lesson, we will go over the measurements of the skull to make it even  more proportionate.)

Pay careful attention to the zygomatic area in the frontal view and make sure that you don't overemphasize it. You might be tempted to make it stick out further than it already does, so be careful!  

Another cautionary area when drawing the skull is making the orbitals too circular and too close together.

You may also discover that you have a tendency to elongate the face area and make it seem much more vertical than it really is.

But remember: this part of the course is intended to be a series of exercises. You’re not creating fine art renderings to be entered into a contest or gallery.  This is simply sketching with a goal of improvement and training your eyes to recognize accuracy. 

Check out the reference that I've provided here as a guide for creating your skull drawing.

You can also look at the quick sketch that I've done in the picture below.

It doesn't need to be elaborate at this point.  Just have a basic understanding of where these anatomical landmarks are.

Portrait Prep Course students- please refer to the "Drawing the Skull" video that was emailed to you.

Muscles of the Face and Head

Now that we have a bit more background about the skull, let's move on to the muscles of the face and head.

If you're overly ambitious and have a lot of time on your hands, this would be an excellent time to learn all the muscles names that make up the face and head. If you’re like me and don’t have that much time to invest, don’t sweat it. All you really need is an understanding of where they are and how they relate to one another. 

There are a couple of areas that have some interesting formations in the face that you will want to notice, outlined in the pictures below. There are some rounded muscles in the eyes, for example. The mouth areas also have some curved types of muscles that affect the way the skin appears in the nose and in the forehead. And then there are some muscles that overlap each other and come together in separate places of the face: the corners of the mouth and some areas in the neck. 

Use the reference below to create a line drawing of the muscles of the head. This will help you gain a better grasp of where these muscles are and how they're positioned in the face.

Skin

The last part of this section is a very brief look at the outer layer of the skin. That layer is affected by certain landmark areas in relationship to the skull and muscles underneath.

 

Some of the most important areas to study skin positioning are the eyes, the mouth, and the nose.

 

The eyes:

The eyeball itself is positioned higher up inside the eye socket. The eyelid actually closes over the upper part of the eye where the top lid will meet the lower lid and produce most of the movement. This is the reason why there are often shadows on the lower portion of the eyeball (the sclera). 

The mouth:

The mouth is more of a cylinder shape and is heavily influenced by the muscles that surround it immediately under the surface.  The muscles get their overall contour from the skull (particularly the teeth, maxilla, and glabella).

The nose:

The nose has a curved area that covers the cartilage.  While the length and side planes of the nose may not seem all that difficult to draw, the underlying structure and make-up of its anatomy is anything but simple.

In conclusion, I hope that this lesson has helped you become more aware of the underlying anatomy of the head and face. When we start to draw a more serious rendering with colored pencil (or another medium of your choice), this knowledge should come back to you and inform your decisions.

We want the knowledge to be sub-conscious and automatic so that we don’t have to think about it when we draw.  We are working towards understanding WHAT we draw so that we can draw what we know.  So we're trying to get past drawing what we see.
