A wind-swept desert dune rises to a sharp ridge, with a curved track of fine hatched lines sweeping through the foreground. Two of the finder squares are drawn as dark square outlines, one on the shaded dune slope and one beside the track, while the rest sit within the dark patches of the ridge. Black ink shapes carry the modules and white sand holds the light areas, so the contrast stays crisp. Tiny stipple dots scattered across the sand add texture without crowding the pattern.
