Cool that you got it so still and in focus, but not a huge fan of the composition. I do realize that composition on a shot like this is so incredibly hard, but still.
Yah, Im not the biggest fan of the composition either, but i do absolutly love how the wings and tail look in this picture.
I must have spent 2 hours following this dude around in my backyard trying to get him in flight. Stupid thing was wicked fast and would always fly the opposite direction that i focused in though. So the ones where he is flying, he is either out of focus, and would have been sharp, or infocus and blured.
