That's my thoughts too - I have never found her pretty - I think her physique is what gets her to be well known as a model, but I don't think her face is anything to write home about. She looks kind of bird like, to me? If you get what I mean?
I just had to google her photos, and she indeed looks like a bird because of her chin, it's a bit too pointed for me. But she has a handful of decent photos. I think with the right make up and angle that makes her chin not too emphasized by lowering her neck, then she will look better in photos.
