I would rate the girl in the 7.5 range. Her face isn't classically pretty, but I don't think her face is busted. If she got some braces, I put her definitely in the 8 range. I think she should do more with what she has in terms of her face and hair (a little make-up, get her hair styled), but with it all packaged together, she's sexy.
