What do you guys think!?
I think I see mis-corrected WB; there appears to be a green cast to most of the skin, the faces seem under-exposed and the expressions, especially of the girl in the white top make me think that you've just told her that she's going to be beaten when she gets home.
I would suggest using longer glass with a larger aperture to more effectively isolate the subject from the background, and especially in #2, put more separation between the two. I would also like too the exposure increased slightly for all three.
