Something under the dunes

A gigantic sandworm with a ringed mouth erupting out of a desert dune, a cascade of sand pouring off it, a lone 4x4 truck racing away across the dunes in the foreground, orange dusk light. The sandworm bursts from the dune and arcs over, sand exploding outward in a wave; the 4x4 races away flat out; the camera chases the truck low, then whips back to the worm as it slams down into the sand.
