Nice bird, background, and sharpness! I would probably remove the bright lines in the right side of the background, and maybe the excrement--but that's personal preference. I also wish the bird was looking more towards you and not slightly away.
Nice earthy tones, good light, perch, BG. I like the pose with erect crest. Too bad the subject is angled away from you and I would also "clean" the perch if that is within your processing ethics.
Neat hairdo and sharp. Needed a bit more head turn towards you. With over the shoulder views 90 degrees is the perfect head angle.
