Wouldn't know about the face, but the hair, yes, there's something slightly odd, dunno, like if she were the only character in the entire game with that hair sty-- oh, wait!
It doesn't matter if it's just her or if there were a hundred NPCs with that style. It doesn't fit with the rest of the art. It'd be like walking through a classical art gallery and coming across a stick figure picture on the wall amongst the other paintings. The difference isn't on that level, but it still doesn't look right when put next to the existing styles we have in the game.
