Overall very good picture. Only a couple problems I have with it.

First off, the proportions seem a bit off to me. Not sure if it's meant to look like that or not, but for instance, the head seems a bit small for the rest of the body. And while on the subject of her head, the other thing I notice is the jawline, it gives her head a sort of off shape if you look at it. And the last thing is the eyes: they seem a bit too spaced out.

Beyond that, this is an extremely cute picture.
