The eyes of some of these women do not look right, or the way the camera shots took them.
I would say that I like, Ohio beauty, because she has a lovely smile and down to earth appearance and just looks approachable....has a nice girl next door type of look and has that fun-loving vibe.
The Brazilian girl does not look pretentious and also appears to look approachable.
There is allot of pictures on the site. Generally, if a woman looks friendly and her eyes do not look too seasoned or intimidating and she has a down-to-earth "girl next door" type of look, then I'm going to subjectively find that women to look more attractive because she has that "don't worry I won't bite" type of vibe. As a guy, approachibility and how friendly the woman looks or how sincere she is coming across weighs very heavily, at least in choosing who I would approach first out of the lot and how I feel the interaction is going to go.
