City Lovers Watercolor Travel Poster

Create a 3:4 vertical scale watercolor urban sketch travel poster on textured handmade watercolor paper.

City Input:
[City Name]

Create a romantic everyday scene that reflects [City Name]'s authentic architecture, landmarks, street life, climate, and cultural atmosphere. Use identifiable city-specific elements such as local buildings, cafes, balconies, canals, bridges, trams, towers, rooftops, tiles, waterfronts, street facilities, plants, or signage. Avoid generic European landscapes or the wrong landmarks.

Main Scene:
The two lovers are shown as the main subjects, positioned slightly below the center. They might be taking a walk, sitting in an outdoor café, sharing iced coffee, standing by the water, admiring the scenery, or gently holding hands. Their poses should feel natural, affectionate, quiet, and unstaged. Don't just show one person.

Roles:
Dress the couple in stylish casual summer outfits suitable for [City Name]: linen shirts, light cardigan, casual pants, summer dresses, sneakers, sandals, sunglasses, crossbody bags, handbags, cameras, pastries, or chilled drinks. The clothing colors are mainly white, light blue, aqua blue, and soft gray-blue, accented with one or two pieces of lemon yellow. Add a gentle breeze to your hair and loose fabrics.

Composition:
It uses a clean vertical poster layout, leaving plenty of negative space and a transparent editorial feel. Keep the couple's ratio small to medium, surrounded by the architecture or scenery of a specific city. Place buildings and landmarks in the background or sides, softly blending into the paper texture. The upper half remains bright and open, with the upper right reserved for typography.

Layout:
In the upper right corner, add the city name in elegant italic English:
"[CITY NAME]"

Next, add a short poetic English sentence that fits the fresh summer vibe of the city. Use delicate and soft cobalt blue, gray blue, or serene navy blue fonts. Keep it minimalist, clear, and blend naturally into the paper.

Color direction:
Use fresh blue-yellow summer tones:

75% cool blue and blue-gray: sky blue, cyan, freshwater blue, pale blue, faded turquoise, soft blue-gray, and localized cobalt blue.

15% clean white and warm white paper highlights.

10% pale lemon yellow, soft cream yellow, sun-kissed milky white, or light golden accents.

Blue should dominate, while yellow adds warmth and visual rhythm. Yellow is used only on canopies, window lights, flowers, umbrellas, pastries, signs, clothing details, beverage labels, or sunlit building edges. Avoid a completely blue flat background.

Watercolor techniques:
Uses semi-transparent gradation, soft blue washing, subtle pigment grains, wet painting textures, soft brushstroke renderings, light shading, clearly visible handmade paper textures, slight splashes, and just the right subtle reflections. Yellow grading should feel like light touching paper.

Painting details:
Delicate ink lines are used, with a slightly imperfect hand-drawn line feel. Add refined urban sketch details: windows, blinds, balconies, streetlights, coffee chairs, paving stones, railings, plants, folds, hair, hands, shoes, bags, cups, signs, and soft ground marks. Keep the face soft and gestury, without pursuing realism.

Minimalist watercolor urban sketch, romantic summer travel poster, quiet love story, city-specific atmosphere, refreshing blue tones with lemon yellow highlights, elegant fashion illustrations, cozy moments of life, soft Japanese style, sophisticated editorial look, calm pastel ambiance, soft natural light, clean background, poster ready, 8K.
