How to use this prompt

The wet-surface reflection is the cyberpunk trick that actually works: 'rain-soaked rooftop' turns every surface into a second light source and doubles the neon, so without it the scene goes dark and flat. Discipline the palette to two complementary neons, cyan and magenta, because if you let Flux run free it rainbow-sprays every window until the city reads as mush. Set the horizon high and keep a foreground rooftop edge so the eye has a near anchor for depth. For the billboards, ask for 'abstract neon glyphs,' not lettering, since real text comes out garbled. The 16:9 crop gives you the wide establishing-shot scale the genre expects.

Variations to try

  • Street-level version — drop to a rain-soaked alley with reflected signage, drifting steam, and a lone figure under an umbrella
  • Daytime dystopia — the same skyline under overcast smog daylight, muted teal and rust tones, the neon switched off
