Post-Apocalyptic Alien Wasteland Warrior

Create a cinematic vertical sci-fi movie poster, showcasing the image.{argument name="character name" default="A muscular, lonely male survivor"} He crouched on the rugged rocks of a desolate alien wasteland. His posture was low and powerful, one knee bent forward, one hand on the ground, the other gripping a black-bladed dagger with a curved bone handle, the tip pointing downwards. His face was covered by a flat, centered, featureless, warm brown rectangular mask, revealing short, dark hair above. Dress him {argument name="armor color" default="Weathered olive green and brown"} The post-apocalyptic wasteland-style armor features heavy, layered shoulder armor, with intricate woven mesh and rope patterns covering the shoulders and chest, along with belts, metal rings, buckles, forearm braces, fingerless gloves, rugged tactical trousers, and heavy boots. A cloak or backpack is worn on the back. The background setting is {argument name="planetary landscape" default="A desolate, rocky desert, with rugged spires and eroded mountains visible in the distance."} Bathed in the golden glow of a setting sun and shrouded in dust, the sky must feature two colossal celestial bodies: a massive rust-orange planet in the upper left background, and a smaller, grayish-brown moon in the upper right. Utilizing epic, high-contrast cinematic lighting effects, the image should feature warm brown and bronze tones, clear and detailed textures, volumetric cloud effects, realistic roughness, a powerful depth of field, and a heroic poster-like composition. The image should not contain any titles, logos, watermarks, or extraneous characters.
