Ken- Well done for capturing the hawk in flight. This is not easy however you "cut" it. The colours of the image are vibrant and quite beautiful. On the capture side, a better head angle would have had the bird looking more at you than away (maybe you have some images in the sequence before this one was made?) and a bit more room to the left would be helpful. Regarding processing I would run some NR on the BG and try to tone down the highlights a bit.
Love the wing display and EXP. He's part the prime location in relation to you or just about. A head turn towards you (yeah, right :) ) would have changed the whole thing. Not crazy about the BG and we need more space in front of him than behind.
