Head: Back View
Draw a circle. Now draw a vertical line at the center of
the circle. Make horizontal dashes at the center of the
circle. A bit below the dashed lines, draw another horizontal
line. (Does this sound familiar? :D)
At the bottom half of the circle, draw the neck with two
lines going down. Now draw the jaw-line of your character
that ends at the neck. If you need to, draw your jawline
till they meet at the center vertical line.
Draw in the ears. Remember, this is the back of the head,
so you have to draw the ears as it would look from behind.
I tend to see it as an elongated letter "C".
Draw in the hair. Notice that in this case the hair covers
the jaw but doesn't cover the ears. For characters with
bushy, long hair, they'll cover the ears too.
Add any accessory - hat, jewelry, etc. - then ink your drawing.
