I'm no expert so take what I say with a grain of salt. I think this photo looks sharp and clear, but I would like to see more of the bird. So I guess I'm saying that the composition could be better :) But perhaps there was nothing you could do about it where you were.
And if you know how to make the photo shows up this big - mine is small and you have to click to see the larger verson :confused: - please let me know.

For such a steep angle you certainly have a sharp and detailed bird. The exposure is great. Now if there was only some way to entice this guy down to get a full view.
