Good-looking specimen and eye contact. I would sharpen the bird more, desaturate the sky a few points and maybe remove the shadow of the branch on the perch.
Axel,
I must admit to wondering about the shadows from the adjacent branches, and I agree that the blue is a bit too blue, but it really was a nice day.
Love the bird and the blue BG. Looks like the top third of the eyes are in shadow and darkening them a bit, but not sure there is much you could do at this point. TFS.
Thanks for all of the positive comments, nothing much I can do about the shadows on the eyes I have allready lightened them, the sun was presumably overhead?
Here is a repost hopefully incorporating your good suggestions, other than the crop. I had allready amended the image before this suggestion arrived:)
