Yep. The faces are a little bit off according to me, too. I think the eyes are OK, the problem is in the noses and mouths. They could be fixed, but somehow they make those skinny bodies stand out even more.
The general effect is a little bit upsetting, but in a good way, meaning that they make you think about current aesthetical models - and how grotesque some of those actually are.
I'd make some modifications to the backgrounds though. I'd either give them the same care of the bodies, or make them blurrier and distant so to make the models stand out.
