### Full prompt
```text
Wide-angle anime sci-fi cityscape inside a completely enclosed [O'Neill cylinder colony], viewed from an elevated perspective looking down the cylinder's length toward a hazy circular vanishing point. The interior surface curves upward on both sides and overhead, filled with dense Japanese-inspired neighborhoods, apartment towers, small houses with red and blue roofs, elevated roads, pedestrian streets, parks, canals, and rail lines. A bright central axial lighting system runs through the cylinder core as three glowing white-yellow light strips, casting soft atmospheric light and immense scale. An elevated train travels on the right foreground track, with tiny pedestrians, vehicles, and warm glowing windows throughout. Integrated readable signage includes three Japanese-style residential district signs, one ramen shop sign, and one "[Neo-Kyoto]" sign. Visual style: [clean detailed anime line art] with crisp ink outlines, cel-shaded coloring, intricate architectural details, slight fisheye perspective, blue atmospheric haze in the distance, capturing a lively futuristic [Neo-Kyoto] mood inside an impossible enclosed megastructure rather than an open sky.
