Travel Poster City Letterform Illustration

Scene:
  Overall poster:
  - 16:9 horizontal travel poster, white or soft ivory background, generous negative space
  - A typography poster themed around '[CITY_NAME]', with the city atmosphere generated automatically from the placeholder city
  - A giant English city name in the center occupies most of the canvas height, while a slim panoramic strip at the top balances the heavy typography below
  Top strip:
  - A narrow horizontal city panorama silhouette, including skyline, cars, trams or trains, with boats added when relevant
  - Add birds, clouds, and the sun; elements are minimal, elegant, and rhythmically balanced
Subject:
  Central typography:
  - The huge English word '[CITY_NAME]' sits in the center of the composition, with tall, elongated, bold sans-serif letters
  - Each letter feels like an individual city gallery window, containing a different illustrated urban scene
  - Streets, landmarks, transit, nature, culture, and architecture connect naturally across the letters, forming a continuous city panorama
  - Letterform edges are geometrically precise, with smooth rounded corners where appropriate, and the layout has a professional editorial feel
  City content:
  - Automatically include iconic landmarks, famous streets, public transportation, urban textures, and local architectural symbols of '[CITY_NAME]'
  - Add bridges, rivers, coastlines, mountains, parks, or other nearby natural elements according to the city’s character
  - Arrange different depths of field and viewpoints inside each letter, combining an overhead map-like feel with side-view cityscapes
Important details:
- Mid-century modern editorial poster style, Swiss graphic design order, travel typography poster and architectural infographic aesthetics
- Pure flat vector shapes, no realistic rendering; simplified building forms, clean geometric shadows, refined linework details
- Center-symmetrical main visual layout, locally asymmetrical but visually balanced overall, with a clear hierarchy between the top strip and the giant type below
- Strong use of negative space, with extremely restrained letter spacing, alignment, margins, and editorial whitespace
- Colors are automatically drawn from the character of '[CITY_NAME]', using soft vintage travel poster palettes and low-saturation combinations
- Use no more than 4–6 colors; coastal cities may use water blue, sand, coral, and muted teal; desert cities may use terracotta, beige, and warm cream; cyber cities may use mint green, navy, and steel blue; historic European cities may use dusty pink, olive green, and parchment
- Screen-printed poster quality, retro-futurist travel brand feel, high-end magazine layout
- Crisp, clean vector edges, geometrically perfect type structure, suitable for printing as a museum gift shop style poster
