I would have made the face narrower, and it's not like she needed such a round face given how poofy her hair is. Also the chin could be longer and mouth narrower. I don't think the nose is as big a deal as people make it out to be. Mostly the overall proportions are off. On the other hand, I looked at the concept art, and the chin/mouth looks better, so it's probably the rigging that's a lot of the issue here.
