Nice color and exposure. It looks reasonably sharp at this size, but there is tonal flatness in some of the grays in the perch and the black area behind the eye. It's not easy to process these birds, with the bright whites and dark blacks.
Can you give information about your processing and if it is a crop (and how much).
It would be more attractive to find a smaller perch -- the large branch isn't the best, especially where it goes out of focus. That could be mitigated somewhat in this frame by a crop of about 1/3 from the right.
