Gorgeous model and nice lighting and diagonals.
Not digging the pose though. Her legs are too close together - maybe one should have been higher on the column so the toes don't get curled that way. The right hand just pops a bit - I'd rather have it under her breasts or on the diagonal beam.
That doesn't mean that the image isn't good though - just take it as a bit of nitpicking from me
P.P. I rarely comment on models, as I find it unprofessional, but wow, just wow.
It's an interesting shot, that is well exposed with pleasing lighting.
However, I too find the pose not flattering. The model is out-of-this-worldly beautiful, but the bent legs don't flatter her, and the hand to the head (especially the arm closest to the camera reaching behind the head) is beyond cliche, and looks incredibly awkward.
I hope you took some more conventional shots with her just standing or sitting, because I agree this was an interesting concept, I don't think it one of your better shots.
