Photograph remote coastal sand dunes shaped by strong wind beneath moonlight. Elegant crescent dunes carry crisp ripple patterns and diagonal ridgelines, with sparse beach grass bending gently and a dark calm sea beneath distant low clouds. Use a landscape 4:3 elevated wide composition, letting foreground dune ridges lead toward the ocean horizon. A bright moon behind thin cloud creates cool silver highlights across the sand and deep indigo shadows, with only restrained reflection on the water. Render fine wind ripples, dry grains, subtle grass movement, and believable coastal geology in photorealistic fine-art night landscape style. No people, animals, footprints, buildings, text, logos, watermark, fantasy glow, patterned stars, artificial light sources, or oversaturated color.
