Nice perch and clean sky BG big pluses as are a handsome bird.
I have no idea if this would have been possible but moving right would have gotten the OOF brush in the LL out of the image and possibly a bit better position of the head and eye to you. Some fill-flash would have been helpful too to compensate for the over the shoulder light direction.
I would try a reverse s-curve to lower contrast some.
Great detail, beautiful bird. Agree with Pieter about lightening the image, as it seems a bit dark on my monitor (MacBook Pro, non-calibrated, brightness set at maximum). I like the perch too, except for the OOF branch in the LLC, as already mentioned. I don't mind the head angle - gives the bird a pensive look.
