I really like this. I like the perch and the way the bird stands on it. All of the technicals look pretty perfect to my eye. I might be tempted to clone out a few of twigs both left and right but its very nice as it is. Congrats on a fine image.
I'm with Dan here especially re the twigs. Not really a huge deal to me but a bit cleaning up wouldn't hurt. Would also suggest running noise reduction on the background.
