Colorful rocket speeders racing across a desert planet

A race of five or six home made rocket speeders on a desert planet. The speeders fly just a few feet off the ground at super high speeds. The speeders have all sorts of different designs and all the speeders are in a very tight race over the colorful desert. Each driver is wearing a colorful helmet and each speeder is painted differently. There are lots of onlookers cheering the race on. There are two moons in the sky. Done in a technical science fiction style along with the color and dynamic of contemporary fantasy art.
