Prompt
Use dark indigo thread on a light even-weave ground, building outlines and tonal regions from repeating counted geometric stitch patterns whose density changes carry the big shapes, with thread and stitch texture visible everywhere. A beach beside tall sand dunes: dunes rising in layered curves with tufts of dune grass at the left, a pale strip of sand, a band of sea with rows of small waves and a wide sky with a few cloud shapes, all stitched in denser and looser patterns.
Light: a bright clear afternoon shown only by stitch density, dense cross-stitch on the shaded dune faces and open weave for the sunlit slopes and the sky, the wave rows as repeating chevron stitches, a single warm ochre thread band as the accent, the dune crest curve as the leading line. Palette of indigo on cream with one warm ochre thread; graphic, tactile, polished embroidery finish.
Wide 16:9 landscape frame. No people, boats, readable text, signs or logos.
