Perfect wing position and lots of detail on whites !! About the only thing I would do is work on the eye? Doesn't appear to have the same sharpness as everything else? Do like the image a lot and could only wish it was mine !! Big Congrats !!
Exposure control and pose look good. I only wish the bird would fly towards you. You probably could have stopped down more for wider DOF since the shutter speed is very high.
