Create a premium cinematic dark-western outlaw poster in a vertical 9:16 composition, styled like a dark western game-character concept poster. Show a mysterious masked cowboy and a black horse at a desert frontier. The cowboy is full-body and front-facing, wearing a low wide-brim hat, patterned bandana covering the lower half of the face, dark long hair, black leather gloves, a black western jacket, layered leather gear, bullet belt, revolver holster, metal belt buckle, heavy boots, and a red-brown geometric-patterned blanket cape with torn edges blowing in the wind. The pose feels calm and dangerous, with one hand near the holster. On the right side, include a half-body black horse with a white forehead blaze and clear bridle details.
Set the background in a stormy western desert with lightning, dark clouds, distant canyon cliffs, dead trees, blowing sand, smoke, sparks, reflective muddy ground, and a heavy epic atmosphere. Split the poster strongly between a vintage parchment blank area on the left and a dark storm scene on the right. Add premium poster layout elements: a large vertical fictional English title, wanted-poster information, character profile text blocks, coordinates, map grid, thin line frames, circular compass graphics, small red markers, and signature-stamp details.
Use black ink splatter, aged paper texture, cinematic realism, dark western mood, strong light-and-shadow contrast, highly detailed leather and metal, dust, mud specks, scratches, smoke, sparks, rim lighting, and an art-book collectible poster finish. Avoid direct references to real games, real franchises, real brands, or copyrighted titles. Output aspect ratio: 9:16.
