This is supposed to be a finished lineart, but I'd like to check the following before I move on. Even though I was cautious this time, I ultimately looked at it a bit too much to recognize my errors anymore:
1. Booty and hips. Did I go overboard with them (so much that it's a bad thing)? (She's supposed to be kind of toned but curvy in the right places.) Would cutting them to the transparent line be enough, if that's the case?
2. Face. Disregarding animoo eyes, does it strike you as uncanny and do you think I should move the ear higher?
3. Her arm. Say, does it look too thin?

Constructive comments about other aspects of the picture would also be appreciated if you have any. If footfag is still lurking here, I'd love to hear his most straightforward evaluation of her legs and feet.
