Battle-Damaged Industrial Heavy Mech

Photorealistic industrial military humanoid mech with heavy armor, bulky proportions, and a low center of gravity. Hard-surface mechanical modeling with realistic engineering details. Massive [yellow] armor showing heavy battle damage: chipped and peeling paint, deep scratches, dents, exposed metal edges, oil stains, dust, and rust on weathered steel and industrial textures. Extremely wide shoulders, thick legs, and a small head recessed into the torso. The right hand holds a massive industrial hammer weapon; the left arm integrates heavy shield plating. Full-body shot in a static, powerful stance amid a post-apocalyptic ruined city with collapsed buildings and rubble-strewn streets. Dramatic cinematic sunset sky with warm orange light contrasting against cold metallic armor. Realistic global illumination, high-contrast lighting, dark gritty sci-fi realism, calm post-battle atmosphere.
