Alien leviathan above a futuristic cyberpunk cityscape

Digital concept art, wide-angle establishing shot. A colossal, biomechanical alien entity looms in the dark, cloudy sky directly above a sprawling futuristic city. The entity features a massive cluster of iridescent, crystal-like compound eyes surrounded by a web of glowing, organic tentacles and translucent tendrils that reach downward toward the skyscrapers. Below, a monolithic cyberpunk metropolis is shrouded in low-lying fog and haze. The city consists of dark, heavily detailed industrial towers with exposed pipes, metallic paneling, and faint warm lights gleaming from scattered windows. The lighting is dramatic and moody, dominated by the bioluminescent, cold cyan and etheric blue glow radiating from the alien creature, contrasting with the subtle warm orange lights of the city below. The sky is filled with dark, dramatic storm clouds illuminated from within by the creature's light. The atmosphere is ominous, apocalyptically grand, and mysterious. High detail throughout, sharp focus on the crystalline textures of the eyes and the metallic surfaces of the architecture, cinematic compositions, 8k resolution digital painting.
