He doesn't seem quite in focus around his beak... that might just be me tho, I've got a hangover! I love the detail you've captured in his feathers, and the background works well too.
Beautifully composed. Very nice details in the feathers. Perfect exposure too Love the splash of yellow in the feather on the head and the inky black eye. Beautiful bird!
This is quite nice, and the only thing that bothers me is that the crop seems a little tight on the left - I don't think it would have hurt the pic to have cut a little more off the wings to give the head a little more room. Otherwise, though, I really like it. Technically, I can find nothing 'wrong' with it - just that 'tight' feeling about the crop (which I know is a personal preference thing).
