One-Light-Year Colony

Create a grand science-fiction space-colony interior scene as a native exact 4:5 vertical gallery-card composition, with masterful composition, cinematic lighting and ultra-detailed rendering. The viewpoint is inside a colossal cylindrical orbital habitat, looking forward through its interior; the scale should feel almost one light-year wide in imagination, with some open structures revealing deep outer space, stars and nebulae beyond. The interior is alive like a new Earth, filled with mist, greenery and organic futuristic architecture wrapped around the cylinder. Avoid straight roads and rigid blocky buildings; every road, bridge and structure should feel nonlinear, winding, curved and complex. Countless small aircraft move rapidly through the air, creating busy high-speed traffic. Use gorgeous light and shadow, extreme macro-to-mega scale, rich city detail, complex facilities and epic megastructure awe. Keep the cylindrical curve, city layers, aircraft traffic, open space window and strongest light shafts inside the central safe area. Avoid flat matte painting, empty corridor, simple straight city grid, copied sci-fi logos, watermark, giant text, cropped cylinder or low-resolution blur.
