Is everything alright with Kate's legs?
I'll be brief.
The problem is the model of her legs. When Kate is standing still and doing nothing, her legs look PRETTY normal.
When Kate crouches or lifts her legs (for example, on a hook), they take a very strange shape. It seems to me that this should not be so because it looks just awful. Why are they getting so fat ?! Just why?
And the last.
Look at the screenshot. I probably leave it without comment.
