i like the background and what you did with 2, but not sure i like the look of the eyes. maybe looking left or right. I realize these are only two of what you shot, but both have closed eyes.
I think one more kiss of light to the back of her head and left arm for separation would have made a significant difference. There are a couple of specular highlights I would try to de-emphasize, but particularly the one on the left breast because it is not casting a golden tone as the others.
Just not diggin' the harsh chin shadow in #2. Certainly not a bad attempt at mood, just not there for me.
