The side view with the slightly turned head presents this this bird nicely. Good and sharp. I agree with toning down the bright spot at the top. If it were mine I also might try and make the lighter circles less obvious. I Also might try a composition with a little cropped off the bottom. If you have it I would add a little behind the bird as it feels a bit tight to me. Thanks for sharing.
Man you were close, 275mm? I usually need 700 for these small birds.
Nice shot, great exposure, HA, background. I might darken that top white area, otherwise nothing to change IMO.
