All three seem to have a little problem with sharpness in the eyes. I'm not sure if that is compression for web or focus, but they just seem soft.
The lighting on the face is nice in all of them.
#1 As everyone has said the leg coming out of her shoulder is disturbing. The whole pose was confusing to me until I saw #2 and figured out what she was wearing. You do use the whole frame, which segues into...
#2 There's a big open spot that drags my eye in the upper left. And the foot is still a problem.
#3 This is the best of the bunch. Nice light, her beautiful face is the center of the image and there is some nice drop off below and behind. Maybe a shade dark in the shadow.
Hope that helps.
