Photoreal Troll in a Subway Tunnel

A photorealistic troll in a dim subway tunnel. The hulking creature stands on the wet, cracked concrete near rusted tracks. Damp brick walls sag with moss and graffiti, flickering fluorescent lights cast cold blue-green hues, steam and mist swirl in the air. The troll has moss-green knobby skin, warts, a tangled beard, yellow glowing eyes, long yellowed teeth, and ragged clothing made of tarp and scrap metal armor. Puddles reflect the creature's silhouette, a rusted subway car lurks farther down the tunnel. Shot from a low-angle, close to the ground, emphasizing the troll's size. Cinematic lighting, ultra-detailed textures of skin, hair, metal, concrete, and water; shallow depth of field with the background fading into darkness; color palette dominated by desaturated blues, greens, and grays; mood: eerie, tense, foreboding.
