I agree that her body did look unnatural and it should have been changed. No doubt about it. But as far as understand Luna is supposed to be quite short. She is 5'5 (165) or something and she looked just about that in the game. I would call women of that height "dwarfs". And more then that, it seems to me later after the second transformation she is again about the same height.
My only gripe is her face. I do think it is worse now. If people don't like hair - change it. If people don't like blush - get rid of it. But what was the point of changing her facial features, her hair color, her skin color, her eyes? Downright stupid. In my opinion, the developer should change all the old pictures in the game with that new model or should return her old face. But the way it is now - part of the game she has one face, part - another, part - the third one. It is just simply ridiculous and stupid.
