Ogre Concept Art in an Underground City

A colossal ogre stands at the threshold of an underground city, ultra-detailed concept art. The ogre is hulking, with moss-covered earth-toned skin, tusks, scars, torn fur, and scavenged iron armor plates. He dwarfs ancient carved stone arches, stairways, and hanging lanterns in a vast subterranean cavern. The city beneath unfolds with bioluminescent fungi, cyan-green crystals, stone towers, arched bridges, and water-filled chasms. Render in cinematic lighting: warm amber glow from lanterns creates dramatic rim light on the ogre, while cool blue ambient light from bioluminescent walls washes the scene. Low-angle perspective emphasizes scale, with extreme detail on rough skin, moss, armor, stone textures, and weathered architecture. Style: fantasy concept art / matte painting, painterly brushwork, 8k quality, deep depth of field with the ogre in sharp focus and background softly blurred. Color palette: cool blues and greens with warm ochre and copper accents. Mood: awe-inspiring, imposing, ancient metropolis hidden beneath the earth.
