Vintage Hangzhou Travel Postcard

Goal: Create a vintage travel postcard poster for {argument name="destination city" default="Hangzhou"}, blending watercolor realism, collage ephemera, and romantic travel-album aesthetics. Canvas: Vertical 3:4 poster on warm aged cream paper with torn, stained, deckled edges, faint handwritten cursive notes, postal textures, watercolor blooms, speckles, and lightly faded ink like an old collectible postcard. Main scene: A young woman seen from behind walks along a sunlit stone path beside West Lake. She has long straight black hair and wears a loose gray open-back top with thin black straps, high-waisted white shorts, and flat sandals. She is centered slightly left, looking toward the lake. The scene is lush and serene: overhanging willow branches fill the upper half, pink flowers and greenery line the path, and soft afternoon light reflects on the water. Architecture and landscape: Show West Lake in Hangzhou with calm rippling water, green hills in the distance, classical Chinese pavilions, a pagoda on a hill, lakeside buildings, and a graceful arched stone bridge at mid-right. Include small wooden tour boats on the lake; use exactly 4 visible boats: 1 large covered boat in the right foreground with passengers, 1 small boat near the center, 1 small boat under/near the bridge, and 1 distant boat on the left side of the water. Left-side street details: Add a rustic lakeside shop façade at upper left with dark wooden beams and red lanterns. Include exactly 3 visible red lanterns: 1 large lantern near the vertical sign, 1 smaller lantern beside it, and 1 small lantern deeper in the shop area. Add a tall vertical wooden sign with Chinese text 「杭州西湖」 and a smaller leaning tea sign below with Chinese text 「龙井茶」 plus English text “LONGJING TEA.” Postcard collage elements: Include exactly 5 distinct ephemera overlays: 1 circular black postal stamp in the upper right reading “CHINA” with Chinese characters and a pagoda illustration, 1 torn map scrap in the lower left labeled “ZHEJIANG,” “HANGZHOU,” “West Lake,” and 「西湖」, 1 small postage stamp in the lower right labeled “CHINA” and “1.20元” with a pagoda landscape, 1 beige poetry card near the bottom center-right with Chinese text 「上有天堂 下有苏杭」 and English text “Above is Paradise, Below are Suzhou and Hangzhou.”, and 1 pink floral paper fragment with cursive handwriting in the upper left. Typography: At the bottom, place a large bold navy all-caps title “{argument name="large title" default="HANGZHOU"}” spanning nearly the full width. Beneath it, add a small copper-brown uppercase subtitle “{argument name="subtitle" default="THE CITY OF POETRY, LAKES & GRACE"}” with thin horizontal divider lines on both sides. Floral foreground: Add white lotus blossoms and pink flowers around the lower right collage area, integrated with watercolor leaves and the postage stamp. Visual style: Retro Chinese travel postcard, watercolor and gouache illustration with realistic proportions, delicate linework, soft natural lighting, muted teal lake water, moss green hills, warm beige paper, navy typography, copper accents, and layered scrapbook textures. Make it look like a future travel album page, nostalgic, romantic, and collectible. Constraints: Keep all text legible, preserve the exact counted elements, avoid modern cars or skyscrapers, avoid extra logos or watermarks, and keep the image as a single finished poster rather than a photo mockup.
