Most Helpful Guy
The photo looks manipulated. They all look as if they've had their faces swapped with someone else's (but maybe it was just that someone retouched it too much and obliterated the texture of their faces). Although the first girl's isn't too noticeable, it looks apparent on the second girl from the left onward and is even more obvious on the girl in the middle onward. I'm not definitive on that opinion though, maybe it was just taken with a cheap camera and bad lighting and someone tried to retouch it more than they should have (given the picture's quality) but that only made it worse. Whatever the reason, it doesn't look natural.
Anyway, from left to right, 6; 2 (She seems to have a good body and great hair, but, because of her huge forehead and large cheeks, her face in this picture looks huge and very disproportionate to the rest of her body. I'd say it was just a bad picture of her and wouldn't be surprised if she actually was attractive.); 6 (Her hair and body are great, but, because light filled her right eye but no light caught her left eye, her left eye looks very strange and her forehead, cheeks, and chin are just unnatural and lack any texture, all of which detracts from her appearance.); 5 (Again, same problem with the other two, only worse. Her cheeks and chin have been so retouched that they lack any texture and the "laugh lines" have been diminished to the point of being barely discernible, which gives her a very fake, plastic appearance.); 7 (Same problem as the last three. Her face lacks any texture and looks very plastic and unnatural).
Overall, I'd say that the girl on the far left, the one in the middle, and the one on the far right (and possibly the girl between the girl in the middle and the girl on the far right) are attractive. As I said, this just wasn't a very flattering picture of any of them.
