The sky blown out is one thing, but for shots like this, I think the yellow cast is perfectly fine if that's the look he is going for. Not everything needs to be "as it was actually seen".
Personally now, I think 1 and 3 are the only keepers pose wise, and only 3 if you can back down the sky so the jump from her hair to the sky isn't so extreme. I think the last pose is awful.
I know that for fashion, models should protract their shoulders, but in this case, she she just looks like an uncomfortable alien... If her body was facing the camera more, I think it would have worked better.
