What a huge eye - great profile too. I don't know if you have access to such a filter but a tonal contrast filter dialled really low would give just a tiny bit of crispness to the feathers. I sometimes used tonal contrast instead of sharpening.
I never noticed that hawks have little eyelashes. Huey, my amazon has the little knob in it's nostril like this. I think that it must be to keep bugs or the like from plugging the nostril. That's a very sharp and detailed photo.
A adore raptors. Whenever my sweetie and I are out and about and see one, we just stop in our tracks. I'll have to upload a shot I took of one on a light post in a small town.
