治愈系柔和水彩城市明信片海报

Create a 3:4 vertical soft watercolor city poster with a warm handmade postcard feeling.

Theme:
A gentle, emotionally warm, minimal city postcard illustration for [CITY_NAME], capturing the city’s unique atmosphere, local charm, and quiet everyday beauty in a simple and comforting way.

Top text:
City name: “[CITY_NAME]”
English emotional phrase: “[ENGLISH_TEXT]”

Typography placement:
Place the city name prominently in the upper area of the poster, either top center or slightly upper-left depending on the composition.
Place the English emotional phrase just below the city name in a smaller, softer handwritten or lightly editorial style.
The typography should feel naturally integrated into the poster, with generous breathing space around it.
Use a handwritten, lightly printed, or softly editorial style that matches the handmade watercolor mood.

Main subject:
A simple, friendly, minimal watercolor scene that clearly represents [CITY_NAME].
Show one main city-specific moment rather than a crowded landmark collage.
The scene should include:
- one signature landmark, street, coastline, hill view, village scene, canal, park, harbor, old town lane, or neighborhood corner of [CITY_NAME],
- one or two small human figures enjoying a peaceful everyday moment,
- and a few local details that naturally belong to the city.

Before drawing, identify the unique city feeling of [CITY_NAME]:
1. one main visual anchor that represents the city,
2. one everyday lifestyle moment,
3. one local environmental or cultural detail,
4. one calm and simple composition that feels specific to this city.

Scene guidance:
Depict [CITY_NAME] as a warm yet refreshing, airy postcard scene.
Focus on one cohesive setting, not multiple landmarks pasted together.
Show a peaceful everyday moment such as walking, sitting, strolling, looking at the view, holding flowers, sharing a quiet conversation, or enjoying the street atmosphere.
Include only a few city-specific supporting details such as:
[LOCAL_DETAIL_1], [LOCAL_DETAIL_2], [LOCAL_DETAIL_3]

Illustration style:
Use delicate pencil sketch lines and soft brown hand-drawn outlines.
The drawing should feel gentle, rounded, simple, friendly, and slightly imperfect, like a handmade illustration.
If people appear, facial details should be minimal: tiny curved eyes, soft rosy cheeks, a small gentle smile, and no overly realistic anatomy.

Color direction:
Use a refreshing blue-and-yellow summer palette.
75% cool blues and blue-grays: sky blue, cyan, pale aqua, powder blue, faded turquoise, soft blue-gray, and selective cobalt.
15% clean white and warm off-white paper highlights.
10% pale lemon yellow, soft butter yellow, sunlit cream, or light golden accents.

Blue should clearly dominate the poster, while yellow adds warmth and visual rhythm.
Use yellow only as refined accents in awnings, window light, flowers, umbrellas, pastries, signs, clothing details, drink labels, or sunlit building edges.
Do not create an all-blue flat background.
Keep the overall tone low-saturation, soft, breezy, and watercolor-light.

Watercolor technique:
Use translucent washes, soft blue bleeding, subtle pigment granulation, wet-on-dry textures, gentle brush blooms, pale layered shadows, visible handmade paper texture, minimal splashes, and delicate watery reflections where appropriate.
Yellow washes should feel like light touching paper.
Preserve a soft handmade postcard feeling with slightly uneven painted edges and visible cold-pressed watercolor paper grain.

Composition:
Reserve clean space in the upper area for the city name and English emotional phrase.
Place the main subject slightly below center.
Keep the background clean and airy.
Add only a few small watercolor doodles such as hearts, dots, stars, flowers, clouds, leaves, or simple underline marks.
The overall image should feel comforting, cheerful, peaceful, refreshing.

创建一个 3:4 纵向、柔和水彩风格的城市海报，具有温暖的手工明信片感。

主题：
一个为 [CITY_NAME] 设计的温柔、情感温暖、简约的城市明信片插画，以简单而舒适的方式捕捉该城市独特的氛围、当地魅力和宁静的日常美感。

顶部文本：
城市名称：“[CITY_NAME]”
英文情感短语：“[ENGLISH_TEXT]”

排版布局：
将城市名称显著地放置在海报的上部区域，根据构图位于顶部中央或稍微偏左上方。
将英文情感短语紧贴城市名称下方，采用较小、较柔和的手写体或轻盈的社论风格。
排版应感觉自然地融入海报中，周围留有充足的呼吸空间。
使用与手工水彩氛围相匹配的手写体、轻盈的印刷体或柔和的社论风格。

主要主体：
一个简单、友好、简约的水彩场景，能够清晰地代表 [CITY_NAME]。
展示一个主要的城市特定瞬间，而不是拥挤的地标拼贴。
场景应包括：
- 一个标志性地标、街道、海岸线、山丘景观、乡村场景、运河、公园、港口、老城区巷子或 [CITY_NAME] 的街角邻里，
- 一两个享受平静日常时光的小人物，
- 以及一些自然属于该城市的当地细节。

绘图前，确定 [CITY_NAME] 独特的城市感觉：
1. 一个代表该城市的视觉锚点，
2. 一个日常生活瞬间，
3. 一个当地环境或文化细节，
4. 一个针对该城市的宁静简约构图。

场景引导：
将 [CITY_NAME] 描绘成一个温暖而清新、通透的明信片场景。
专注于一个连贯的设置，而不是多个地标拼接在一起。
展示一个平和的日常瞬间，例如步行、久坐、散步、观赏美景、拿着花、分享一段安静的对话或享受街道氛围。
仅包含几个特定于城市的辅助细节，例如：
[LOCAL_DETAIL_1], [LOCAL_DETAIL_2], [LOCAL_DETAIL_3]

插画风格：
使用精致的铅笔素描线条和柔和的棕色手绘轮廓。
绘画应感觉温柔、圆润、简单、友好且略带瑕疵，像手工插画一样。
如果出现人物，面部细节应尽可能简略：细小的弯弯眼、柔和的红润脸颊、小小的温柔微笑，且没有过度写实的解剖结构。

色彩方向：
使用清新的蓝黄夏日配色方案。
75% 的冷蓝色和蓝灰色：天蓝色、青色、淡水色、粉蓝色、褪色绿松石色、柔和的蓝灰色以及点缀性的钴蓝色。
15% 的干净白色和温暖的米白色纸张高光。
10% 的淡柠檬黄、柔和的黄油色、阳光下的奶油色或浅金色装饰。

蓝色应在海报中占据明显主导地位，而黄色则增添温暖和视觉韵律。
仅将黄色作为精致的点缀，用于遮阳篷、窗户光影、花朵、雨伞、糕点、招牌、服装细节、饮料标签或阳光照耀的建筑边缘。
不要创建全蓝色的平铺背景。
保持整体色调低饱和、柔和、轻盈且具有水彩的通透感。

水彩技巧：
使用半透明的晕染、柔和的蓝色渗色、细微的颜料颗粒感、干叠色纹理、柔和的画笔水渍、浅淡的分层阴影、可见的手工纸纹理、少许溅渍以及适当的精致水面反射。
黄色晕染应感觉像光线触碰纸面。
通过略微不均匀的绘画边缘和可见的冷压水彩纸纹理，保持柔和的手工明信片感。

构图：
在顶部区域为城市名称和英文情感短语留出干净的空间。
将主要主体放置在稍微偏离中心下方的位置。
保持背景干净通透。
仅添加一些小水彩涂鸦，如爱心、圆点、星星、花朵、云朵、叶子或简单的下划线标记。
整体图像应感觉舒适、愉快、宁静、清新。
