So who hasn't seen a lot of nudes? Like flowers, it will be judged, at least unconsciously, against all the others that the viewer has seen. As far as this one goes, the face is nicely in focus, and it's the only part of the body that is, which lends a feeling of seduction and softness. I guess the hand is in focus, too, but I doubt a lot of people will gaze longingly all day at the hand. Your lighting is excellent. I too feel that the lamp is a distraction.
The lighting and skin tones are superlative, just a shame the sheer elegance and beauty of the model was not framed against props that do her some justice! This photo is all about her face - isn't it just. Strip away the flotsam and jetsam, and crop to that awesome beauty... it's a winner.
