Class 4 session 01: Face animation

I've added eyebrow animation first, I am trying to stay away from "swimmy" animation by having no more than 5 in-betweens within the facial expressions and having slight drifts, visible in the graph editor but not that much in the animation.

On the first half of the shot I played with the mouth facial rig, I still don't know how all the controls work, what it does and what doesn't. I need to get familiar with it.
