Impressionist oil painting, landscape 4:3: layered snow-covered mountain ranges under a winter night sky, the Milky Way arching in a luminous band above the peaks, deep indigo and violet sky filled with crisp stars, moonlit snow ridges glowing pale blue; thick visible oil brushstrokes, impasto texture on snow and rock, cool blue shadows against warm amber light from a tiny distant cabin window; atmospheric depth, no people, no text, no watermark, no logo.
