Here is a demo reel of a facial rig I recently put together.Facial Rig Demo Reel from Daniel Vaughan on Vimeo.
To get some practice animating a face I've used a scene
from the television series Firefly and broken it down frame-by-frame, then I've
tried to copy the facial movements of Kaylee, the main focus in the scene. The
scene I've used is from the episode 'Shindig', this scene's quite good as she
pulls a range of different expressions.
