Anime Moonlit Swordsman: Bamboo Grove Duel

Modern anime key visual illustration, vertical 4:5. A cool-headed anime adult swordsman character in his late twenties with long black hair in a low ponytail, a fine scar through one eyebrow, ice-calm grey eyes and an elegant lean build, drawn in refined seinen anime style. He wears a dark indigo kimono with a plain white sash, a katana with undecorated guard at his hip and straw sandals, original design without crests. He stands in a moonlit bamboo grove in a relaxed ready stance, two fingers resting on the katana hilt, leaves falling around him in slow arcs. In the foreground, falling bamboo leaves and a stone lantern glow at the frame edge. In the midground, the swordsman in focus, kimono folds and hair in exquisite line work. In the background, towering bamboo in layered blue-green depth, a full moon through the stalks. Camera and composition: side-profile anime key visual, full-body with grove depth. Lighting: moonlight shafts in pale silver, lantern warmth as a single accent. Materials and texture: detailed cel shading, painted bamboo textures, silk sheen on kimono. Style: seinen anime key visual, moonlit indigo palette, lethal serenity. The drawing is finished to key-visual standard: confident line weight variation, hair rendered in sculpted strand groups with two-tone cel shading, eyes with layered highlights and gradient irises, and background art painted with enough detail to hold its own beside the character. Composition follows anime key-art discipline: a clear focal silhouette, diagonal energy through the pose and environment, atmospheric effects like drifting leaves, sparks or rain integrated into the light, and a palette limited to a few harmonized families so the image feels designed, not decorated. Clean line art, detailed cel shading, cinematic composition, no text anywhere in frame.
