That's a nice shot. The off-centre framing gives the sense of motion down and to the left and stops that 'static' feel that you can sometimes get when trying to capture something moving fast.
Th plane is nicely framed and the background is gorgeous, but for me they don't go together. The deep green of the background would work better with a silver-colored aircraft. Thsi ends up being a bit drab for me--this plane needs a lighter background. The propeller effect is cool!
I would have liked a richer green in the background myself. This isn't a compositied image, no PC magic other than color/saturation/contrast/sharpness was done.
