Very rarely does nude photography appeal to me. It's not that I'm offended by it at all -- for some reason, it just doesn't appeal to me. But this one is so beautiful -- it looks like a print in a gallery. The lighting is exquisite, and of course the beauty of the girl and her comfort in front of the camera doesn't hurt.
I like this one better, the lines are more complex, the legs make strong leading lines, and the hip is especially good. Both suffer from a fall off of light at the feet, and the highlights on the face are a bit too hot.
It's a tough call because they are both very good, but I think I like this one better. The pose of her legs is just superb and the lighting works very well with the pose. The lighting is also great in the one you chose for the challenge, but the elegant continuous lines of her legs are much better portrayed in this one.
