Gregory I find the sticks infront of the birds beak a bit disstracting. The lighter on heading in the same direction as his beak and then the one crossing over. You could clone them out leaving the birds head and beak against the light blue background which would show up the great clarity you have achieved.

I'd also cut a little off the top and some of the left hand side and technically there should be a little added to the right and to the bottom so the bird is more looking into the photo rather than out of it.

Great clarity and great capture Gregory.
