โปสการ์ดท่องเที่ยวสไตล์การ์ตูนย้อนยุค

Vertical retro cartoon travel postcard for [Chengdu] in a bold vintage comic-book style with thick black outlines, bright pop-art colors, visible halftone dot texture, slightly grainy aged print, and playful exaggerated perspective. Sky: saturated cyan-blue with comic dots and exactly 5 cream-and-peach puffy clouds (one large cloud on the upper left, one large cloud on the upper right, one partial cloud entering from the left middle edge, one small cloud left of center, one small cloud right of center). Lettering at the top: huge arched yellow block letters reading "[CHENGDU]" with black shadow and outline; directly underneath, red Chinese characters "[成都]" flanked by two red dots. In the upper right corner, a red circular postal stamp reading "WELCOME TO CHENGDU" with a cute panda face and three wavy postal cancellation lines. Center background: a tall TV tower rising behind a giant faceted, geometric stone-like panda-head building featuring black ears, eye patches, and a blue doorway at its mouth. Lower skyline: colorful simplified modern buildings and lush green trees. Foreground left: a traditional Chinese pavilion with green tiled roofs, hanging red lanterns, and Chinese signage; beside it, a roadside sign reading "I ♥ CHENGDU" with a cute cartoon panda mascot standing and waving. Foreground right: a yellow vertical street sign with Chinese characters "[太古里]". Across the bottom: a bright blue river with stylized wavy white highlights spanned by an arched cream stone bridge on the right. Composition is dense, cheerful, and legible like a souvenir postcard, with no photorealism and no extra text.
