Joe: I really like this image. Nice job with the exposure holding the whites. Love the wing position and the sharpness is great. Congrats on a great image.
The wing position does set this image apart.
I echo Sid's opinion about lighting up the bird. I should separate it better from the BKGR, which is my only nit.
Great shot nonetheless!
