Neon Cyberpunk Troll in a Skyscraper Atrium

Inside a neon lit skyscraper atrium a colossal cyberpunk troll towers over steel beams and glass. It has moss green skin with metallic implants, glowing cybernetic eyes, LED tattoos, a jagged prosthetic arm, and rugged urban armor. Rain streaks the exterior glass; holographic ads swirl in the air; chrome elevators glide between floors. The perspective is from a mid level looking up to emphasize scale, with reflections on wet floors and blue magenta neon lighting. Cinematic lighting, ultra detailed textures, 3D render, concept art, gritty dystopian vibe.
