Overall pretty nice, but I would prefer the comp as a vertical. In this orientation the subject would need to be smaller in the frame or in a different, less erect pose (and yes further to the left) as it is too tight top and bottom. Amazingly beautiful colours on this guy...WOW!
I love the OOF background. The head angle on the bird is great. Would have a little more appeal if the head angle was just a few degrees more towards you. I lthink the detail in the feathers and the color saturation are wonderful. . Love the lighting and the pose. Excellent job. You might possibly think about cropping this into a vertical
