I love portraits like this! I like the crop and the wonderful detail and sharpness . Great detail in the whites! Maybe darken the pupil a little? I'm not sure what it should look like, though.
I really like the streaking background as it crosses and parallels with the birds neck curves. And you did well with those white feathers. Very nice shot and not much more I can say.
Lovely shot indeed. Great pop and sharpness on the eye and beak. Not sure yet why I like the BG, but I do. I'm especially impressed how you handled the whites on the bird.
