Pretty cool to see the ways his wings are adjusting his direction in flight, but as a photo I can't find much to like, especially in a challenge like this one.
Not sure what is going on but looks like this was a serious crop or missed focus because of the lack of detail in the bird and the heavy noise in the sky. The eye is also very dark, brighten up the eyes of animals/people to draw the viewer in.
What a graceful pose! Seems as though it may have been cropped a fair amount because the feathers seem to be lacking a bit of detail, the overall impact of the photograph is good.
