Oh my.. I like this very much. Wonderful pose you captured. The background enhances this image. I like it very much. It feels just a bit tight in the frame. Congrats on a fine image.
This is a stunning image. The composition works fine for me. The only nit that I have is that I would smudge/clone out the horizontal line of the BG, the one leading into the birds head; but honestly it doesn't bother me that much. Congrats on an amazing photo
