Sharp, well exposed, nice angle in frame, good display of the strong feet, pleasant background.
Nice detail in the log, but it is pretty massive and I might do some cropping(left, bottom and right) to downplay that a bit.
I don't mind the perch size at all (I like big perches such as rocks, stumps, or logs when they are nicely anchored to the bottom of the frame), but I would have placed the subject further left of the frame and with more room above. Beautiful subject with great plumage, and I love the BG. Was this fella attracted to a setup?
A new bird for me; I always enjoy that! Good sharpness and a nice pose. I like Daniel's idea about the placement of the bird in the frame. Have you tried a vertical crop?
