Stunning looking shot however whats up with the little hint of black feathers on his back was that a photoshop error? How did you do your color separation?
lovely and sharp with the parrot... Personally I don't like the greyed out background as I think it's a bit overdone these days. Nevertheless, the colours on the parrot are amazing.
C&C I really like the processing to bad the Bird wasn't working with you, his pose really hurt the shot. Next time maybe try multiple shots (if you didnt) and watch your composition, you cut off his tail feathers.
I would try to maybe darken the blacks a little in the B&W part. I think the bird would pop more. I would also try backing off the saturation on the yellow ever so slightly. Other than that it looks great. Good Job.
