Here is a constructive criticism: you should perhaps not state a preference for constructive criticism over favorable comments. There may come a day when you get no favorable comments, and then you will wish mightily that you might have some.
Love this shot but you asked for constructive criticism. The only thing that wasn't perfect to me is the cropping of her head. Now, I like good cropping, but this shot has everything else and it seems a little abrupt - most cropped bodyscapes that I like zone in and also cut off feet and other elements - and I think the effect could have been done by her turning her head or having her hair cover her face (but then having her entire body and head in the shot).
But please note this is a minor thing, the shot is really great as it is.
The lighting is perfect. In fact, the white background lets you focus completely on the body. The hand gestures and pose of the legs are different, letting you see and enjoy the beauty of both. The stockings are a great touch. Normally, I might prefer them to go up the thigh but in this case, they accent the legs which we definitely want to see more of. I like the semi refection on the floor which seems almost like a frame for this very attractive form. Great work!
Good pose, nice simplistic clothing lighting is good too and of course the model is sexy ^^. Infact the only drawback to me is the fact that her head is cut out. I think it ould have been nicer if she was complete (she could have turned her head to the other sid to protect her privacy).
