Stone Age Watercolor Owl in a Cave

An owl perched on a gnarled branch inside a shadowy Stone Age cave, painted in luminous watercolor. The owl's feathers are rendered with soft washes and delicate texture, using earthy tones—ochre, burnt sienna, olive greens, and muted blues. The cave walls are streaked with primitive pigments and charcoal outlines, featuring simple rock-art motifs of mammoths, spears, and paw prints. Light filters through a small crack, creating a warm amber glow that bleeds into the paper, giving a luminous ancient feel. The composition blends realistic owl detail with rough prehistoric cave-art ambiance, as if a prehistoric artist captured a nocturnal moment on rough handmade paper.
