Create a vertical 9:16 Y2K-era editorial collage poster for [City Name]. Use a cut-and-paste magazine collage style with a fictional clearly adult street-fashion model as the central sticker cutout. Place the model in front of a black-and-white halftone city skyline background. Add colorful ransom-note paper letters spelling [City Name] across the top, plus sticker-like urban icons such as a drone, high-speed train, local food, drink cup, street signs, tech-hub badge, city-style buttons, barcode strip, and small editorial label blocks. Use bold mixed typography, paper textures, halftone dots, sticker borders, layered scraps, denim-and-mesh Y2K fashion styling, playful city branding, and an energetic editorial poster layout. Keep all readable text fictional or based only on [City Name], avoid real logos, and keep the composition polished and high-quality for GPT Image 2.
