I really enjoyed the compositions on these. She looks quite natural in all of them; no forced poses. I looked at your flickr site, too, and there were a couple there that I also like - especially the one with her laying her head flat on the bed.
The first two here seem a bit soft to me. I don't think I'd want them super sharp for this type of shot, but maybe a bit less soft would be better. Just my amateur opinion!
i dont know much about posing people for this type of portrait but 3 seems the best pose to me, i think i like this kind of tight shot to have eye contact.
I think they are all lacking in contrast though. Not sure how you wouldn't do it but I would use curves and not the contrast slider, the curves tool retails shadow and highlight detail and spreads the mid-tones out.
