复古成都卡通明信片

Create a vertical retro cartoon travel postcard for {argument name="city name" default="Chengdu"}. Use 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. The sky is saturated cyan-blue with comic dots. At the very top, place huge arched yellow block letters reading {argument name="headline text" default="CHENGDU"}, with black shadow and outline; directly underneath add red Chinese characters {argument name="local city text" default="成都"} flanked by two red dots. In the upper right, add a red circular passport stamp that says “WELCOME TO CHENGDU” with a cute panda face and three wavy postal cancellation lines. The scene should show 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, and one small cloud right of center. Center the postcard around Chengdu landmarks: a tall TV tower rising from behind a giant faceted panda-head building, with a blue doorway at the panda’s mouth; make the panda head geometric and stone-like with black ears and eye patches. Along the lower skyline, include colorful simplified city buildings and green trees. On the left foreground, include a traditional Chinese pavilion with green tiled roofs, red lanterns, and a sign with Chinese characters. On the right foreground, include a yellow vertical sign with Chinese characters {argument name="landmark sign text" default="太古里"}. Across the bottom, draw a bright blue river with wavy white highlights and an arched cream stone bridge on the right. In the bottom left foreground, place a roadside sign reading “I ♥ CHENGDU” and a cute standing panda mascot waving beside it. Counted visible elements: 1 main headline, 1 Chinese subtitle, 1 red passport stamp, 5 clouds, 1 central TV tower, 1 giant panda-head building, 1 traditional pavilion, 1 vertical landmark sign, 1 river, 1 arched bridge, 1 “I love Chengdu” sign, and 1 waving panda mascot. Keep the composition busy but legible, like a cheerful tourist souvenir postcard, with no photorealism and no extra text beyond the specified lettering.

创作一张 {argument name="city name" default="成都"} 的竖版复古卡通明信片，以该城市标志性的熊猫主题地标为核心焦点。采用可爱稚拙的儿童绘本风格，建筑造型极简，运用厚重的几何形状、夸张的比例、极简的细节、粗犷的黑色轮廓线、波普艺术色彩、可见的半调网点纹理、略带磨损的复古印刷颗粒感，营造出欢快的旅行海报氛围。 画布：竖版 3:4 明信片构图，背景为明亮的青蓝色点状天空。顶部三分之一处为巨大的拱形标题文字 {argument name="headline text" default="CHENGDU"}，采用暖黄色填充，配以黑色阴影和粗黑轮廓。正下方添加红色中文字符 {argument name="local city text" default="成都"}，两侧各有一个红点。在右上方的天空中，加入一个红色的圆形邮戳，印有“WELCOME TO CHENGDU”字样，配以简单的熊猫脸图案和三条波浪形邮戳线。 主体场景：画面中心是一座高耸的电视塔，从巨大的几何熊猫头建筑后方升起；塔身细长，设有圆形观景台，点缀橙色细节，顶部有一根细天线。熊猫头建筑呈低多边形石块质感，黑白配色，圆耳朵，黑色眼圈，小鼻子，嘴部区域为蓝色玻璃入口。设置台阶从熊猫建筑向下延伸至前景的蓝色河流。 前景与城市元素：包含 5 朵奶油色的蓬松云朵，带有浅桃色阴影和半调网点：左上角一朵大云，右上角一朵大云，左侧中部边缘一朵局部云，中部附近两朵小云。除中央塔楼和熊猫建筑外，增加 2 个主要地标建筑：左下角一座色彩鲜艳的中国传统凉亭，配有绿色瓦顶、红灯笼和带有中文字符的招牌；右下角一座横跨河流的奶油色石拱桥。地平线两侧点缀简化的柔和色调城市建筑，外墙为黄色、青色、珊瑚色、蓝色和橙色，带有微小的黑色窗户。右侧包含一个竖向黄色招牌，上面写有黑色中文字符“太古里”。下层场景填充圆润的亮绿色树木和灌木，点缀粉色小花，并勾勒黑色轮廓。 吉祥物与标志：在左下角前景处，添加一只可爱的挥手熊猫吉祥物，站在一块矩形标志旁。标志必须准确写有“I ♥ CHENGDU”，配以红心和黑红相间的块状字体。熊猫拥有白脸、黑耳黑肢、粉红脸颊、张开的笑脸以及一只举起的手掌。 风格限制：保持所有形态简洁且具有图形感，如同复古漫画明信片。使用饱和的黄色、红色、青色、蓝绿色、奶油色、绿色、珊瑚色和黑色。所有物体均需保持强烈的黑色轮廓线，边缘呈现手绘的不规则感，整幅图像覆盖丝网印刷的半调纹理，拒绝照片写实主义，拒绝精细的写实建筑细节，除指定的标签外，不得添加任何额外文字。
