I took a similar image a couple of years ago with a canon rebel xti. I am amazed by the amount of detail I am now getting with the 7D.

Hi Jay,
I would like to see more room in front. The whites are blown on the leading edge of the left wing. I like the dynamic pose and the dangling feet. I would lighten the dark bit in the top BG as it draws the eye to that area,
