Cyberpunk Troll in a Mountain Cave

An imposing cyberpunk troll stands in a shadowy mountain cave. Jagged rock walls glow with neon runes and cables snake along the surface. The troll features cybernetic implants: one glowing visor, exposed circuitry under rough gray skin, a riveted metal arm, and a strapped data pack on its back. A tattered cloak hangs from broad shoulders. Bioluminescent moss and crystalline minerals spill cyan and magenta light across the scene. Mist drifts through the air as rain beads on the rock. Through the cave mouth, a distant neon city glows with pink and blue lights, reflected on wet stones. The image is gritty, cinematic, highly detailed, with moody lighting and a fusion of fantasy and high tech.
