I really like the pose. Might have been better as a "nude" since there are really no body parts showing. The socks and shirt are distracting. Also, it looks like the hair is held up somehow. Would have liked to see the subject in a more natural state, but the pose is interesting.
I find it a little difficult to spot anything in this picture that's sharply in focus. You may well have meant it that way, but I find it distracting. Having gone through some contortions, I have to add that I'd prefer to see this the right way up, as I feel that it works better that way.
Wow, a different type of bridge! I like this shot a lot, but would also like to see a little sharpness added. I love, love, love the way you framed with her legs and little footies.
