Anime Serpent Guarding a Stone Fortress

An anime-style snake with large, expressive eyes and shimmering emerald scales, coiled around the crenellated battlements of a grand stone fortress. The fortress towers glow with torches and fluttering banners as dusk settles. The snake's head is raised, tongue flicking, gaze intense toward the viewer. Dramatic lighting, cel-shaded anime aesthetic, vivid colors, wind-swept flags, mist in the valley, and a dynamic low-angle perspective that makes the fortress feel imposing. Details include moss on stones, a distant moon, and a subtle magical glow around the serpent.
