I like the look-down pose and sharpness. I might lighten the underside of the bird a bit more and remove what looks like a greenish cast. As for composition, I would put the bird further to the left and crop some off the right and run NR on the BG.
The cast seemed more yellow then green and was hard to deal with :) Image quality is on the poor side and all looked too light to me. I do like the pose.
