可爱复古成都卡通海报

Create a cute retro cartoon travel-poster cityscape of Chengdu, 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 “CHENGDU” 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.
