Interesting pose and great detail in the wings.
If it were mine, I'd reposition (canvas extended on right), get rid of the green band at top, lightly overlay the white band through the bird, and apply a little Nik Color Efex 4, a little surface blur on the background, all with masking. No additonal sharpening needed.
This is what I'd envision....
I enjoy the flight pose quite a bit. Don's repost is an improvement imo, especially in regards to
the removal of the green band at the top of the frame. His repost has a strange little white strip
at the top right hand side, but otherwise looks great.
I'm on my work monitor (horrible) so won't comment on the techs, but I love the pose with the eye showing through the forward swept wings. Good capture.
