Blood-Red Western Gunslinger Poster

Create a vertical western action character poster in Rockstar Games official concept-art style, polished hard-boiled graphic novel rendering. A confident male gunslinger, {argument name="character identity" default="a faceless placeholder man with a smooth tan rectangular mask covering the face"}, stands in a low-angle heroic pose occupying the lower 75% of the frame. The top 25% must remain a strictly empty solid blood-red sky with no text, logos, clouds, or objects. He holds exactly 2 ornate long-barrel revolvers: one raised upright in his left hand on the viewer’s left, and one raised upright in his right hand on the viewer’s right, both with engraved gold-and-steel details and ivory grips. Attire: {argument name="outfit" default="cream off-white wrinkled button-up shirt, dark navy neckerchief, wide dark leather gun belt with two buckles, black trousers, and a brown leather holster on the left hip"}. Background: {argument name="setting" default="red desert canyon with tall rocky spires and saguaro cacti at sunset"}, dark silhouettes and orange rim light behind the character. Composition should crop close from thighs to above the head, with the head centered, shoulders broad, weapons extending toward the upper corners, and the viewer looking upward at the character. Use dramatic chiaroscuro lighting, heavy ink-like shadows, warm orange highlights, painterly halftone texture, gritty western poster finish, sharp costume folds, detailed leather tooling, and no readable text or watermark.
