The Circle

Drawing a circle to begin the head is taught in almost every art book I've ever read. But it is important to remember that the circle is just a rough outline. You should never fully rely on a circle. But it is a good place to start. If for nothing else, it works great to figure out the placement of a head.

Beginners Hint:
Sketch lightly if you plan on erasing the pencil.

The Center Line

This is in fact the most important line. This line will not only help point your character in the right direction, but it will also help you draw in the face evenly.
Draw this line first. It will set you up for the eye line.



The Eye Line

The eye-line is the second most important of the lines.
The eye-line should be placed under the middle of the circle. But this will change as you change the size, and the angle of the head.



The Ear Line

This one is simple enough, though I would not recommend sketching this one in. Its easy enough to imagine in place. As soon as your jaw-line hits the circle's edge it goes upwards.

Beginners Hint:
Remember that the ear is drawn under the eye-line.



The Nose Line

Again, I would not recommend drawing this one in. The nose line will change depending on how your drawing the head, so its better to go without.

Beginners Hint:
If you plan on making the mouthed closed, then try putting the tip of the nose right between the eye line and chin.
If you plan of making the mouth open, then put the tip of the nose a little higher.

 

Remember to think of the circle as a solid sphere. Always try and 3D it in your mind's eye. You'll get better at it as time goes by.
