Great shot, one comment - the bird's smack dab in the center. Maybe recrop with more space on the right and a little off the bottom. Just so the bird is a little off center. But a really nice image.
Very nice bird indeed. Love the open beak and clean BG. My only suggestion would be to crop a bit on bottom. For some reason the yellow blobs on BG are complementary with the spotting on breast of this bird, at least for me.
A very nice capture. I agree about maybe a bit more space on the right. I like the BG although I would tone the green down a bit but that is a personal thing and in noway distracts from the shot. Great looking bird.
