Nice image. On the technical side, not sure if you were going with a slower shutter to show the motion. I would like to see with a faster shutter to get the full effect of the water and better detail on the wings.
A very good action shot that falls just short of being a technical success. A difficult lighting problem with the flatish green background in combination with a odd lighting angle. Some of the body details are lost in dark while others aren't apparent at all. A good entry into the challenge that falls just short of being a technical and artistic success.
