I like the puffed up feathers, good eye contact on his right, soft background.
I think the image could go a bit brighter, about 1/3 of a stop, and would consider adjusting the shadow and highlight sliders inward just a bit, gives it a bit more snap.
It would be nice to see the tail, but sometimes its a trade off to cut down the clutter.
In a perfect world, wish the little stub wasn't sticking up in front, minor really.
