Interesting pose and nice light. I would give it more room at the bottom and darken the bright spot in the lower left. You could apply some NR on the BG. It looks as if the nictitating membrane is covering the eye.
This is a really neat pose. I like it. On my monitor, it seems somewhat soft as if too much noise redux. If you are using Neat Image or Noise Ninja you might consider using them in advanced mode. I find it helps me not to over sharpen feathers.
Very good. I like it mainly because I havn't seen a similar one before. If you take ,any flight shots for Example, many photos look alike, just a few sticks out.
(My screen on this computer is too bad to see if it's noisy eycetera so I am happy.)
