What a nice looking bird, you've caught a great wing position here. I believe that the bird is a bit dark overall, but nice and sharp. I look forward to seeing more of your images.
Beautiful subject and I agree with Grace that i's a bit dark. Also, using Selective Color if you went a few points negative with the black it would open up the shadow areas as well.
Great flight pose, excellent sharpness and if the head were turned more optimally, this would be a real stunner.
Great flight shot, love the spread feathers on the near wing. As Grace and Jim point out, can definitely go lighter on the bird, but would leave the background as is.
