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.
