Cute Retro Chengdu Cartoon Poster

Create a cute retro cartoon travel-poster cityscape of [city name], in a naive children's picture-book style with ultra-simplified chunky architecture, exaggerated proportions, bold thick black outlines, bright flat colors, halftone comic-paper texture, slight ink misregistration, and a sunny turquoise-blue sky. Use a vertical 3:4 poster composition. At the top, place huge arched yellow bubble letters reading “[headline text]” with black shadow, and beneath it red Chinese characters “成都” flanked by two red dots. Make the clear central focus a stylized panda-head building inspired by Chengdu panda landmarks: a large geometric white-and-black panda face structure at the bottom center with a blue glass entrance, stairs, shrubs, and flowers, with a tall slim TV tower rising directly behind it. Include exactly 3 panda motifs: the giant panda-head building, a small cheerful waving panda mascot in the lower left foreground beside a sign, and a red circular passport-stamp graphic in the upper right that says “WELCOME TO CHENGDU” with a panda face. Include exactly 5 puffy cream clouds with peach shading: one large cloud on the upper left, one large cloud on the upper right, one partial cloud entering from 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 colorful rectangular buildings in teal, yellow, pink, orange, and blue, plus green treetops. Add a traditional Chinese pavilion on the lower left with green tiled roofs, red lanterns, and a small sign with Chinese-style characters; add a yellow vertical building sign on the right reading “太古里”; add a cream arched bridge over bright blue water on the lower right. In the lower left foreground, place a sign reading “I ♥ CHENGDU” next to the waving panda. Keep all forms rounded, toy-like, and geometric, with minimal detail, thick outlines, warm cheerful colors, vintage postcard energy, and no photorealism.
