Really nice lighting and exposure. I like pretty much everything about this photo, but something about the way the branch is "posed" in the frame bugs me. Maybe I'd rather see more, or see less, of the branch, but since I can't put a finger on it then that usually means it's not an important part of the overall image.
Thanks Aiden. I agree, I thought about including the whole fork, but then the bird would have appeared too small... I also thought about cloning out the left branch, but didn't want to fumble with that nice BG.
