The colors pop, the HDR was done with class, and isn't overpowering like the majority of HDR's, the DOF looks nice (although it looks fake how shallow the background is, which I assume was post), and the subject is isolated from the background nicely (albeit done by fake shallow DOF). Though the photograph is beautiful in these areas, I think the only thing that severely injures it is the composition. This is only my opinion, but when an object is not either bulls-eye center, in one of the corners, composed centrally with good symmetry of surroundings, or some other extenuating circumstances, it appears to be somewhat novice. Don't take this the wrong way, as I am not saying that this photograph is novice, because it is obvious that it was taken by a skilled photographer, but to me, I think if the bird were located less centrally in the composition it would be improved upon heaps.
I know that this may seem like a harsh review, but I just wanted to give one that was thorough.
