I like the pose and BG. Maybe a bit more sharpening? Is this a heavy crop? There is not much detail in the plumage. I'm wondering what other people think about it.
What a cute bird. Love the markings and crest on this little fellow. Lovely pose and head angle, a beautiful bg, and perfect exposure. I think you did a very good job on composition in this image. You could not have eliminated the branch terminal without clipping the birds tail, and I think you included just enough...
any more, and the bird would have been too centered. Does need another round of sharpening, but I like this image a lot.
