I decided to merge the first ten pages of the tutorial into one long strip. I think it looks good.
This pattern will likely continue, making each page its own submission, then combining the next ten into another strip.A brief summary of pages 1-10:The head
Draw it as an ellipse (a stretched circle) about 4 units tall to 5 units wide.
Rotate the head to create the angle you want; rotating just the facial features looks really wonky.The eyes
The eyes follow perspective. When the head is facing to one side, the eye on that side will be smaller since it's farther away.
When staring straight ahead, both eyes are the same size. As the face tilts up or down, the eyes rotate like circles drawn on a ball.
When the head rotates left/right and
tilts up/down, combine these two techniques to get the right effect.The hairline
Just as the eyes rotating enhances the 3D illusion, the hairline curvature does the same. Facing up or down means the hair curves up or down respectively.
The hairline moves lower on the face if facing down. It also moves up or disappears if the face is facing up.
