Had some more fun with Ps, this time paying more attention to the spin of the rear wheel and its effect on the tire smoke. In this one I was going for more of a stationary camera with a much lower speed for the rider; so no motion blur throughout the environment.

I was going for realism, please let me know how close I got.
This is also the first one I've used some grain in. It seemed to even out the billows of smoke, making it seem not so ...um... plastic? Again, looking for feedback, and feel free to be critical.
