Cute Retro Chengdu Cartoon Poster

Create a cute retro picture{argument name="city name" default="Chengdu"} This cartoon travel poster adopts a naive and charming children's picture book style, presenting simplified, heavy architecture, exaggerated proportions, bold black outlines, bright flat colors, a halftone comic book paper texture, slight ink misalignment effects, and a clear blue sky. It uses a 3:4 vertical poster composition. A large yellow, curved bubble at the top reads, "..."{argument name="headline text" default="CHENGDU"} The image features a black shadow and the Chinese characters "Chengdu" in red below, flanked by two red dots. The central focus is a panda-head-shaped building inspired by Chengdu's panda landmark: a large geometric black and white panda face structure at the bottom center, complete with a blue glass entrance, steps, shrubs, and flowers, with a tall, slender TV tower standing behind it. The image must include three panda elements: the large panda-head building, a cheerful panda mascot waving from beside a sign in the lower left foreground, and a red circular passport stamp in the upper right corner with the words "WELCOME TO CHENGDU" and a panda face design. It must contain 5... A collection of fluffy, creamy clouds with peach-pink hues: a large cloud in the upper left, a large cloud in the upper right, a partially obscured cloud at the lower left edge, a small cloud near the left-center horizon, and a small cloud near the right-center sky. At the bottom, construct a simplified skyline in cyan, yellow, pink, orange, and blue rectangular buildings, along with green treetops. Add a traditional Chinese pavilion with green glazed tiles, red lanterns, and a small plaque with Chinese characters in the lower left; add a yellow vertical building sign reading "Taikoo Li" on the right; and add a creamy-colored arched bridge spanning a bright blue body of water in the lower right. In the lower left foreground, place a sign that reads "I ♥ CHENGDU," next to a waving panda. Maintain all shapes and sizes as rounded, toy-like, and geometric, with minimal details, bold outlines, and warm, bright colors, exuding the vibrancy of a vintage postcard, without any realistic elements.
