Architectural poster 3D city retro elegant

Objective: create a stylish retro travel poster for , presenting with a refined Japanese tourism aesthetic. Canvas: wide horizontal poster, 16:9 ratio, warm off-white paper background, with delicate retro texture, using a soft color palette of sage green, pale cyan, beige, peach, soft gray, and deep slate outlines. Layout: at the top, draw a slender panoramic skyline spanning almost the full width. It should contain a total of 12 groups of clearly visible landmarks from left to right: a stone-walled Japanese castle with pine trees, low-rise urban buildings, modern high-rise buildings, factory chimneys, commuter trains, long bridge decks, cable-stayed bridge towers and cables, orange port cranes, small industrial towers, more port buildings, a huge peach-colored sun, and distant city towers. Above the skyline, add a few small birds and simple line clouds. Main typography: the center of the poster is dominated by the huge word , in bold compressed uppercase letters, with wide and tall letterforms and tight letter spacing. The letters act as cutout windows, filled with detailed city illustrations inside. Use 9 letters: A, M, A, G, A, S, A, K, I. Inside the letters, show scenes inspired by Amagasaki City, including castle moats and stone walls, shopping street signs, pedestrians on crosswalks, city buildings, railway lines and stations, towers, statues and plazas, rivers or canals, bridge trusses, factories and chimneys, port cranes, riverside trees, high-rise apartment buildings, and cherry blossoms. Keep the masks inside the letters clear to ensure the word remains legible. Subtitle area: below the huge city name, center small and widely letter-spaced sans-serif uppercase letters , flanked by thin horizontal lines. Below that, add an even smaller and widely letter-spaced uppercase tagline . Bottom icons: at the bottom center, include 6 small pictogram icons separated by thin vertical lines: 1 castle, 2 shopping bag, 3 train, 4 bridge, 5 factory, 6 trees. Use the same soft colors and simple line art style. Visual style: a combination of elegant mid-century travel poster and Japanese architectural illustration, precise thin ink outlines, flat colors, slight weathered print texture, balanced negative space, steady composition, no realism, no 3D rendering, no heavy shadows, no watermark.
