Very nice detail and interesting character. Great background. I wonder if you could get away with a bit more sharpening around the eye area in particular? Also, IMO, you could have kept the perch above the bird, as I now find it a bit truncated. Even better would have been a perch that didn't go behind, but that kind of thing is always wishful thinking!
Very cool bird and great image. I like the colors and detail. It seems the sun was a bit high when you took the picture, but it's clear that sometimes it is what it is and the only chance you get for a photo is when the sun is high.
I noticed some burned highlights below the wing, I wonder if they could be removed in PP. I also wonder how it would have looked with the perch going above the bird.
