Neon Falls in the 1920s Cyberpunk Speakeasy

Inside a hidden 1920s speakeasy carved into a cavern, a colossal indoor waterfall roars through a glass wall, casting refracted neon reflections across velvet booths, brass rails, and Art Deco chandeliers. The atmosphere fuses cyberpunk and Jazz Age glamour: a live band in retro-futuristic outfits, flapper patrons with cybernetic implants and glowing jewelry, cigarette smoke curling through the humid air. Outside, the rain-slick city glows with holographic billboards; neon pink, cyan, and amber lights shimmer on the mist. The bar features chrome-tipped taps and cocktails that glow with nanolume. Style is cinematic cyberpunk neon-noir, hyper-detailed digital painting with sharp focus on the waterfall and reflective surfaces, dramatic backlighting, volumetric mist, and a slightly low camera angle sweeping toward the cascading water.
