Architecture poster comic urban retro cute

Create a cute retro cartoon travel poster of , using an innocent children's picture-book style, presenting ultra-simplified heavy architecture, exaggerated proportions, rugged black outlines, bright flat colors, halftone comic paper texture, a slight ink misregistration effect, and a clear cyan-blue sky. Use a 3:4 vertical poster composition. At the top, place giant yellow curved bubble lettering that reads "", with a black shadow, below it the red Chinese characters "成都", with a red dot on each side. The center highlights a panda-head-shaped building inspired by Chengdu's panda landmark: at the bottom center is a giant geometric black-and-white panda face structure, with a blue glass entrance, steps, shrubs, and flowers, and a towering slender TV tower rising behind it. The image must include 3 panda elements: the giant panda-head building, a happy panda mascot waving beside a sign in the lower-left foreground, and a red circular passport stamp graphic in the upper right reading "WELCOME TO CHENGDU" with a panda face design. Include 5 cream-colored fluffy clouds with peach shadows: one large cloud in the upper left, one large cloud in the upper right, one half-hidden cloud at the lower-left edge, one small cloud near the left-middle skyline, and one small cloud near the right-middle sky. Build a simplified skyline along the bottom, with rectangular buildings in cyan, yellow, pink, orange, and blue, plus green treetops. In the lower left, add a traditional Chinese pavilion with green glazed tiles, red lanterns, and a small plaque with Chinese characters; on the right, add a yellow vertical building sign reading "太古里"; in the lower right, add a cream-colored arch bridge spanning bright blue water. In the lower-left foreground, place a sign reading "I ♥ CHENGDU" next to the waving panda. Keep all shapes rounded, toy-like, and geometric, with minimal detail, rugged outlines, warm bright colors, full of vintage postcard energy, and without any realistic elements.
