Great feather detail and the whites well handled. The bird sits well in it's environment. If I were being really picky I might suggest losing the small green patch to the right of the bird. Lovely image.
I like the resting pose with the raised back feathers, pretty cool. A bit more room to the left would have helped the comp IMO, and I do find the image oversharpened as posted, with crunchy details on the face.
