The light strikes me as somewhat flat, there's not a lot of modeling going on in her face. Given that she doesn't have a particularly dramatic bone structure to start with, I don't think this lighting does her any favors. Also, this sort of thing - straight on, fairly close in - is going to emphasize the heck out of any asymmetries in the model's face. Her eyes are distinctly different shapes, and it shows, and that's not particularly flattering.
She would be better served by a pose with her face turned, at least slightly, and by a more dramatic lighting ratio, I feel. Actually, just about ANYONE is better served by it, the point is that only bizarrely perfect people really look good in this sort of photograph, and while she's very very pretty, she's not a weirdly perfect person.
That said, there's a truth to this sort of thing. If you want to make a picture that acknowledges the asymmetry we all have, and yet still shows her as beautiful, this might be getting into the general area.
