I also rigged and animated these two characters for HER Interactive. I have to make a very loud shout-out to Mark Dygert (aka Vig), the Animation Lead over at HER. He taught me more about rigging, lip sync and Motion Builder in three months than I've ever been able to accumulate on my own. He's a one-man 3D orchestra. If you're ever up on Polycount.com, he's the senior dawg and he goes by Vig.
Each of these characters were modeled, zbrushed, and textured in two business weeks....80 hours. Another week to rig and create morph targets and about a week and a half to two weeks to lip sync, body pose, and animate. It was an extremely aggressive schedule but it worked out and I hear from those that matter that they're happy.
