What a nice look at that huge foot!! I agree with more room all around (hopefully you have enough to see the extra twig attached to the main perch...if not, it can go), and I'd apply some NR to the BG (noise especially visible at the top half of the sky)
Thank you for your constructive comments. Unfortunately there is no room left at top and bottom of the original pic (unless I add canvas) but I can certainly create more room in front of the bird and, Daniel, maybe it is a good idea to get rid of that branch.
