She is just extremely homely. There's something wrong with her eyes that indicates a lack of sleep, those masculine features wouldn't even be attractive on a man, and she refuses to close her mouth in her 'candid' shots, so it just makes her look worse. There's nothing wrong with slightly crooked teeth, but it's not a good crown to the rest of that.
Seriously, you don't have to put on heavy make up for every picture, but at least put some minimal effort into looking presentable if you're going to show off how conventionally attractive you are.
A couple extra notes: she has the look of a young boy when looking at her nose-up, and she absolutely should not ever, ever cut her hair short like this. Long, feminine hair is a necessity to offset her manly features.
