AI Prompt for Post-Apocalyptic Sci-Fi Warrior Poster

"Create a cinematic vertical sci-fi movie poster of {argument name="character name" default="a muscular lone male survivor"} crouching on a jagged rocky outcrop in a desolate alien wasteland. He is posed low and powerful, one knee bent forward, one hand braced on the ground, the other hand gripping a curved bone-handled knife with a dark blade pointed downward. His face is deliberately covered by a flat, centered, featureless rectangular mask in warm brown tones, while short dark hair remains visible above it. Dress him in {argument name="armor color" default="weathered olive-green and brown"} post-apocalyptic armor: bulky layered shoulder plates, intricate woven netting and cord patterns across the shoulders and chest, leather straps, metal rings, buckles, forearm bracers, fingerless gloves, rugged tactical pants, heavy boots, and a cloak or pack draped behind him. The setting is {argument name="planetary landscape" default="a barren rocky desert with distant jagged spires and eroded mountains"}, lit by a dramatic golden sunset with dust and haze. In the sky, show exactly two large celestial bodies: one enormous rusty orange planet dominating the upper left background and one smaller gray-brown moon in the upper right. Use epic high-contrast cinematic lighting, warm sepia and bronze color grading, sharp detailed textures, volumetric clouds, gritty realism, dramatic depth of field, and a heroic poster composition with no visible title text, logo, watermark, or extra characters."
