Create a 9:16 premium cinematic western outlaw poster in the style of a dark western game character concept poster. Show a mysterious masked cowboy and a black horse standing at a desert frontier. The full-body figure faces forward with a low wide-brim cowboy hat, patterned face scarf covering the lower face, dark long hair, black leather gloves, black western jacket, layered leather gear, bullet belt, revolver holster, metal belt buckle, heavy long boots, and a red-brown geometric patterned blanket draped over the shoulders with torn edges blowing in the wind. The pose is calm and dangerous, with one hand near the holster. The black horse appears half in frame on the right, with a white forehead marking and clear bridle detail. The background is a stormy western desert with lightning, dark clouds, distant canyon cliffs, dead trees, sand, smoke, sparks, and muddy reflections, creating an oppressive epic atmosphere. Split the image with vintage parchment blank space on the left and the dark storm scene on the right. Add premium poster layout elements such as a large vertical English title, wanted-poster information, character dossier, coordinates, map grid, thin line frames, circular compass graphic, small red marks, and signature stamps. Use black ink splashes, old paper texture, cinematic realism, dark western mood, strong light-and-shadow contrast, ultra-detailed leather and metal, dust, mud spots, scratches, smoke, sparks, edge rim light, collectible game-poster quality, and artbook concept-sheet texture. Avoid protected franchise names or real brand logos.
