It's definately better. As far as the lips, on your model's lower lips, there appears to be darker areas on each side. I'm thinking that maybe her lip is 'pouted' forward (front to back along the z axis) a little too much and causing shadows. I'm not sure. I do know that when I watched the movie last Friday (my 4th time) I noticed that although Liv's lips were big on the y axis, in the profile shots they didn't look thick on the z axis. I don't know if your models' lips are thick or not but I figured I'd mention it. I know, I'm being hyper-picky. She looks great as is! I mentioned that because I don't know how far you want to take her. I wish I could get this close. Those gorgeous lips kinda make me wish I was virtual. And single.

Before they made me they broke the mold!
