Nice contorted hunting pose. This guy looks very concentrated on its potential meal. The smoothed-out look of the plumage on the face and neck make it appear like NR was applied to the bird too (normally it should be done to the BG only).
Beautiful pose; good underwing detail; same comment on sharpness of the bird; some extra sharpening (or losing the inadvertent NR) will improve it a lot; personally I would tone the green in the BG down a tad, but that is really just personal pref. I won't mind owning this one.
