Looping Coastal Dunes

Finished editorial ink-and-marker illustration, 2:3 portrait, straight-down aerial view of one coastal dune system. Three connected apricot dune ridges sweep diagonally from the lower left toward the upper right, with comically oversized rounded lobes, long narrow necks and asymmetric contours. A tiny cobalt-blue interdunal pond nestles inside one loop, its mirror-still surface indicated by one clean pale reflection mark, no ripples. A narrow cobalt sea edge enters along the lower-left border, separated from the dunes by a simple irregular shoreline. Broad lavender ground remains open in the upper left for breathing room. Bold, slightly wobbly dark-purple ink contours, flat marker fills, just a few curved crest lines and sparse grass ticks to identify the dunes. Legible at thumbnail size. No gradients, 3D shading, intricate hatching, paper collage, cream or beige backgrounds, teal-and-terracotta palette, people, text, logos or watermarks.
