Concept Skates

This was my original concept for the strobist.com transportation bootcamp assignment. I only have one flash and quickly learned that this just wasn't going to cut it. I eventually took a more conventional shot which I entered.

 

The question is, can anybody come up with a way I could have made something like this work with only one flash? The idea was to show off the blue transluscent wheels and to also get the triangular shadows on the ground.
