Interesting preening pose...looks like a tough spot it's trying to reach! The kink in the neck looks a little awkward - but it does add to seemingly difficult reach :-) I'm finding the crop a little tight, and would have loved it if you had pointed your lens slightly higher and right.
Beautiful light and the HA makes this work for me. Sharpness also tops. I agree on giving the bird a bit more room, and I would turn the image around (?).
