# play with straights and curves, playing one off the other
# tend to have half of the face squashed and the other half stretched.
# make sure all the parts of the face work together to form a clear expression
# have the eye lids mimic the brows and direct the eye line
# break up the timing on the parts of the face, have something lead as the other part follow
# break up the timing on the areas of the parts ( sides of the mouth, or face)
# use eases and overshoots for the parts of the face
# have the brows lead the action of the head and eyes
# try to add in contrast with opposing squash and stretch
# Rule #1, make sure your emotion reads clearly.
# Do all aspects of the face support that emotion, do the different parts work as a whole? Are you hitting the necessary markers/indicators for the emotion you're trying to portray?
# What leads what: offset keyframes to tell the story. For example: the brows almost always lead the emotion, so after selling the thought in the eyes, start the tranformation of the face with the brows.
# Spot Light your emotion: Help your emotion read by
1.) Expression Changes get lost in motion, Never stage an important face change to take place in mid-motion, make the change before or after the motion
2.) As a rule of thumb, no expression change in the first or last 8 frames of the scene. It takes about this long for the audience to get oriented.
