post-apocalyptic style

A giant modern Colosseum made of polished concrete and neon, illuminated by spotlights. In the arena, two cybernetic gladiators in high-tech exoskeletons, one with an energy shield, the other with a plasma sword. The arena floor is covered with digital markings. The stands are filled with a crowd of fans holding glowing gadgets. Dynamic angle, cyberpunk night city atmosphere, detailed lighting, highly detailed, cinematic quality.
