great facial expressions! I wish I could see the rest of the body to give more feedback.
You have very nice stylization! Love how smooth your lines are. And the expressions are wonderful. Keep it up!
I like number 83 the best. There is a decent flow to the body and the pose is interesting.I think you do a great job on faces and I would focus on full body images instead of facial ones. I too like drawing faces a lot, but you need to work on being less timid with the body proportions by drawing more of them. Right now, I would worry more about the basic figures and less about the details in faces, hands and clothing.
I basically agree with everybody's been saying. Love the faces, would love to see more possesses. However since you're working with film a lot, I can see why would wouldn't have them. The only thing I can add is perhaps go back on some of the drawings and add some marks for shadows, nothing too dramatic but something to give a sense of light. But that's optional.
