Rainy Cyberpunk Rooftop City

Create a cinematic cyberpunk city rooftop at night in a rainstorm, wide 16:9 establishing shot from a low eye-level camera, with a wet reflective concrete surface dominating the foreground. The scene is a dense futuristic metropolis filled with tall dark skyscrapers, blue haze, mist, rain, and volumetric atmosphere. Use neon magenta and electric cyan lighting, physically based rendering, hyper-realistic 3D CGI, Octane-render quality, live-action sci-fi blockbuster aesthetic, high contrast, glossy reflections, puddles, subtle lens bloom, and moody depth of field. The rooftop contains exactly 6 prominent foreground/midground elements: 1 large black horizontal cylindrical tank on the left under pink strip lights, 1 chain-link fenced structure behind it with a glowing Japanese neon sign reading left_neon_sign_text, 1 small utility booth near center-left, 1 low metal railing and barrier line across the middle, 1 glowing magenta vending-machine-like light box on the right, and 1 bulky rooftop antenna or mechanical equipment tower on the far right with magenta highlights and dangling cables. In the background, include many high-rise towers but emphasize exactly 3 readable billboard areas: 1 enormous central vertical digital billboard showing a close-up face of a young woman with a short black bob haircut and pale skin, 1 adjacent vertical magenta sign with abstract glyph-like markings, and 1 smaller upper skyscraper sign reading brand_sign_text. On the giant central billboard, include bold white text reading billboard_number, Japanese text reading billboard_japanese_text, and a name below reading billboard_name. Composition should have no people physically present on the rooftop, only the billboard face; keep the color palette deep navy, black, cyan, and hot pink; make the ground mirror the neon signage clearly; avoid daylight, warm sunlight, cartoon styling, or clean pristine surfaces.
