I thought that was you :) It is so very beautiful! I agree with Mark -- ridiculously underrated! What's with these voters -- there's no appreciation for true artistry!
The lighting is great. The tone is great. The pose isn't so great. I don't understand the concept of turning her head. The arm that is viewed is seems ill posed and should be closer to the body or more interesting.
One of the better images in the Challenge, imo. The techniques were used together well to great effect. The missing arm (if there's an arm there?) is maybe a little odd to the eye but overall, I like the shot.
