Good capture, well timed. The crane sticking out the top left of the car is a little distracting, but I guess this is a photo you can only take once right :-)
More lighting on the bottom half of the picture would help make the subject pop out more. The top of the vehicle has some vivid colors. If there was more light it would help give it more interest. The crane in the background is a bit distracting. I like the dirt flying as the vehicle jumps. It gives a good sense of motion and speed.
I see what you were trying to capture...however I believe all the background [crane, truck] are distracting. the color is good and the idea is very good. Yes, I do see this as flight. Good.
