City Adventure 3D Poster AI Image Prompt

Theme 3D poster, overall with refreshing sky blue, fluorescent green, milk white, and bright yellow accents. The main subject is a creative ticket titled 'City Adventure'. The upper half of the ticket features simplified city transportation symbols (high-speed rail, bus, taxi, plane). A circular frame shows a natural map route. A rounded rectangular window in the middle opens as an entrance from city to nature: the left side faintly shows the city, while the right side extends into grassland, hills, lakes, tents, and sunshine. Two chibi-style young people burst out of the creative vertical curved ticket window, as if just escaping the city. Their expressions are relaxed and happy, and their clothes are vividly colored to enhance realism and depth. The title 'City Adventure' is in large slanted typography with cartoonish deformation and a naive style. The subtitle 'Go on an adventure this weekend!' accompanies it. Surrounding decorations include dashed route lines, location pins, hand-drawn arrows, small flowers, ticket number patterns, and bright yellow sticky notes. Overall young, fun, and highly shareable. Center focus, strong perspective, 4K HD. No logo.
