Beautiful image. LIke the composition, nice lines and angles complimenting each other.
Could remove a little off the top. There is a little blotchiness happening in your background.
Love these birds.
I like the angle, pose and BG. I would put the bird further to the right in the frame and tone down the whites a bit more and wish for a bit more head turn towards you.
I agree with the comments above. It seems that there is a loss of details in the feathers due to noise reduction (?). I like the perch and pose of the bird :-)
Thanks for your comments folks but there was no NR, and almost no PP, simply reducing the size of an almost unaltered photograph from 21 M/Pixel to its present size does the trick every time, I wish I could find a way around that.
