Hair in Action:
Hair can be
a very useful visual cue for describing motion and adding a dynamic
element to your art. The trick is to show how the hair follows
the direction of the head. If the character is falling..the flow
of the hair is the opposite direction. if the character is blown
backward, the hair shoots forward...see?
(p.s. forgive the high quality cocktail napkin art over here..I
just wanted to use this to make a point)
