This is a very dynamic, well composed shot. The angle is unique, as is the pose. The leg in the back helped avoid the illusion of looking at half a woman (which would have been the case without it). The contrasting from bright on top to dark at the bottom bathed the subject in extremely complimentary light, and helped create very sharp definitions and boundaries. There was just enough back-fill light to illuminate and not let the in-frame light overpower the shot. Very nicely done!
Great work with light. Nice pose and model.
