Nice and sharp and the flash has lifted him nicely from the BG, Dan. Agree with Stu on a bit of eye doctor work. Could maybe pull back on some of the sharpening a bit.
Challenging bird to photograph, as they rarely seem to sit still. I think Tony hit the nail on the head with his critique; slightly oversharpened with a too-prominent catchlight from the flash. I might try warming the color temperature a bit.
