Prompt
A vertical minimal desert scene rendered as a digital painting for a 2:3 poster-cover, with a single broad dune occupying the lower third and tapering toward the left third of the frame to create subtle diagonal flow. The center and upper two-thirds are open sky with a gentle horizontal gradation from warm sand hues near the horizon to cooler muted teal near the top, keeping negative space in the upper-right third. Lighting is soft and even, like late golden-hour glow diffused through haze, producing long, soft shadows along the dune crest and smooth tonal transitions across slopes. Textures are restrained: fine sand grain visible in close bands along the foreground ridge and satin-like, almost polished surfaces on distant dunes. Composition uses a wide-shot, eye-level viewpoint with moderate depth, where the nearest dune fills roughly 30–40% of the vertical frame and background dunes recede into soft atmospheric haze. Keep edges clean and minimalist, no added props or text, and present the color harmony as warm ochre, pale cream, muted teal and deep shadow brown for print-ready poster output.
