Neon Bridge in a Cavern: Cyberpunk Grotto

Ultra-detailed cyberpunk cavern scene featuring a sleek neon-lit suspension bridge spanning a deep underground chasm. The cave walls are carved rock with dripping water and bioluminescent minerals that glow purple, cyan, and magenta. Stalactites shimmer above; mist swirls in the air. The bridge has glass panels, glowing rails, exposed cables, and holographic signage; anti-grav mag-rails hum beneath. A shallow underground river reflects neon light; puddles mirror the bridge and rock textures. Drones and maintenance bots perch on the structure. In the far background, distant city-arcades glow through tunnel mouths. Cinematic, wide-angle shot, low perspective, photorealistic textures, high detail, filmic lighting, color grading to neon blues and magentas.
