I like the image composition with the angle in frame, inclusion of tree line to anchor the image.
The lighting well off to your right has given him nice definition, but cast the face in shadow somewhat.
The primary feathers on the upper wingtip look a bit beat up. Did you have to do some work there?
Great comp, and I too like the treeline included at the bottom. Needs a bit more sharpening to bring out the fine detail for web posting...is this a big crop?
