I've been working off and on, on a rig for a face model from TurboSquid (Thanks to the folks at Bitmapworld for making such a nice model!) After unwrapping it and finally finishing the rigging I got to start animating it. The whole goal was to create a subtle and "realistic" animation. I'm pretty happy with it, and I plan on continuing the quest for subtlety.
You can look at some of the progress of it Here.
