A 2:3 vertical campaign poster blending real photography with flat doodle illustration, styled like a city tourism ad (similar vibe to TfL "Your London Adventure Starts Here", reimagined for Shanghai). Background: an unretouched realistic low-angle hero photograph of the Oriental Pearl Tower across the Huangpu River, Lujiazui skyline behind it, tower centered and vertical with its two pink spheres clearly visible. Shot at early evening blue hour, city lights just starting to glow, sky still holding daylight, natural reflections on steel, concrete and river. The sky sits as a deep teal-to-indigo gradient with a subtle warm horizon glow, the upper 40% of the canvas kept open for headline copy, no filter, no retouching. Giant cartoon hero character standing on the right side, roughly 1.2x the tower's height, body extending past the canvas edge. She holds a cartoon bamboo xiaolongbao steamer basket up to eye level in one hand while the other hand does a casual wave, one foot slightly lifted mid-step. Flat neon-green skin (non-realistic). Minimal face: a single curved smile, no nose, small cobalt-blue dot eyes. Long straight black hair with hot-pink streaks pulled into a high side ponytail, short blunt bangs. She wears an oversized cobalt-blue modern qipao-inspired cropped jacket with stand collar and hot-pink frog-button closures, off-white baggy cargo pants with a neon-green side stripe and oversized pockets, and chunky pink-and-yellow platform sneakers. Thin consistent black linework on qipao collar, frog buttons, ponytail strands and steamer weave. The steamer basket has three xiaolongbao peeking out with tiny yellow steam swirls drawn above. Flat cartoon doodle props layered over the photo: - Lower-left foreground: three oversized cartoon soup dumplings floating together with exaggerated steam swirls, off-white skin, hot-pink pleats, sun-yellow steam, tilted, partially covering the tower base. - On the lower pink sphere of the Pearl Tower: a flat sticker restyling the Shanghai Metro red circle mark, hot-pink circle with off-white Chinese character 地 inside and neon-green sparkle stars. - Mid-left, floating in front of the tower mid-section: a stylized cartoon Huangpu river wave curl shaped like a chunky comma, cobalt-blue body with off-white foam tips. - Center-upper, overlapping between the two pink spheres of the tower: a round traditional cartoon red lantern (hot-pink) with a sun-yellow tassel and neon-green string. - Far-left mid-height: a small cluster of 3 oversized cartoon magnolia petals (Shanghai's city flower), off-white with hot-pink tips, drifting diagonally as a color accent. - Bottom-right near the character's shoe: a tiny cartoon bubble tea cup with a smiling face, ink-black pearls, neon-green straw with a panda-ear topper, acting as a sidekick scale cue. Copy on the poster, set into the open upper sky area: bold Chinese headline "你的上海奇遇 从这里开始" up to three lines (English variant "Your Shanghai Adventure Starts Here"), subhead "乘地铁。逛街巷。尝一口。" beneath. Bottom-left logo lockup: "上海市人民政府 SHANGHAI MUNICIPAL GOVERNMENT". Bottom-right logo lockup: "上海地铁 SHANGHAI METRO — 每一站都是故事" with metro roundel. Overall aesthetic: realistic city photograph as base layer, bright flat-color cartoon doodles, characters and stickers sitting on top in a playful campaign-poster composition. #AIart #GPTImage2

一张 2:3 竖版活动海报，将真实摄影与扁平涂鸦插画融合，整体风格像一张城市旅游宣传海报（类似伦敦交通局 "Your London Adventure Starts Here" 的氛围，但为上海重新演绎）。 背景：一张未经修图的真实低角度英雄式照片，内容为隔着黄浦江拍摄的东方明珠塔，背景是陆家嘴天际线，塔体居中且呈竖直姿态，两颗粉色球体清晰可见。拍摄于傍晚蓝调时段，城市灯光刚刚开始亮起，天空仍保留着日光，钢铁、混凝土与江水有自然反光。天空呈现深青色到靛蓝的渐变，地平线带有微妙的暖色辉光，画布上方 40% 留空以容纳标题文案，不加滤镜、不做修图。 巨大的卡通主角角色站立在画面右侧，高度约为东方明珠塔的 1.2 倍，身体延伸出画布边缘。她一手举着一只卡通竹制小笼包蒸笼到眼睛高度，另一只手轻松挥手，一只脚微微抬起呈现迈步状态。皮肤为扁平的霓虹绿色（非写实）。极简脸部：仅有一条弯曲的微笑，没有鼻子，小小的钴蓝色圆点眼睛。黑色长直发带有亮粉色挑染，扎成高高的侧马尾，刘海为短齐式。她身穿一件宽松的钴蓝色现代旗袍风格短款立领夹克，饰有亮粉色中式盘扣；下身为米白色宽松工装裤，带霓虹绿色侧条纹和超大口袋；脚穿厚底粉黄拼色松糕鞋。在旗袍领、盘扣、马尾发丝和蒸笼编织处使用粗细统一的黑色线条。蒸笼里有三只小笼包露出，旁边画着小巧的黄色蒸汽涡旋。 叠加在照片之上的扁平卡通涂鸦道具： - 左下前景：三只超大卡通小笼包汤包一起漂浮，蒸汽涡旋夸张，米白色外皮，亮粉色褶皱，向日葵黄蒸汽，倾斜摆放，部分遮住塔基。 - 在东方明珠塔下方粉色球体上：一个扁平的贴纸，将上海地铁红色圆形标志重新演绎为亮粉色圆圈，内嵌米白色汉字「地」，并配有霓虹绿色闪光星星。 - 中部偏左，漂浮在塔身中段前方：风格化的卡通黄浦江波浪卷，形状像一弯粗大的逗号，钴蓝色主体，米白色浪尖。 - 中上部，叠在东方明珠塔两颗粉色球体之间：一盏圆形传统卡通红灯笼（亮粉色），配有向日葵黄流苏和霓虹绿色挂绳。 - 左侧中段高处：一小簇 3 片超大卡通玉兰花瓣（上海市花），米白色带亮粉色尖端，斜向飘动作为色彩点缀。 - 右下靠近角色鞋子的地方：一只小巧的卡通珍珠奶茶杯，带笑脸、墨黑色珍珠、霓虹绿色吸管，配熊猫耳朵装饰，作为配角比例提示。 海报文案，安排在上方留空的天空中：粗体中文主标题"你的上海奇遇 从这里开始"，最多三行（英文版 "Your Shanghai Adventure Starts Here"），下方副标题"乘地铁。逛街巷。尝一口。"。左下角标志组合："上海市人民政府 SHANGHAI MUNICIPAL GOVERNMENT"。右下角标志组合："上海地铁 SHANGHAI METRO — 每一站都是故事"，并配地铁圆形标志。 整体美学：以真实城市照片为底层，亮色扁平卡通涂鸦、角色和贴纸叠加在上方，构成活泼的活动海报版式。 #AIart #GPTImage2
