1. The exposure on the skin and top is just a tad hot; I'd try and pull the whites & highlights back just a bit in LR. I would also get rid of that bit of brush that's creeping over her left arm.
2. Mehhh... I see what you were after here, but I don't think it worked. Between the blown/nearly blown top, too hot chest and zero detail hair, I'd bin this one.
3. Better on the exposure; I just wish she'd taken the time to run a comb through her hair! Watch your backgrounds; the bright white stripes are a real eye-grabber and are pulling attention from the model.
