Shanghai Travel Poster Collage

Create a premium vertical travel-poster collage for SHANGHAI, CHINA on a warm textured cream paper background. IMPORTANT COMPOSITION: The design must be clearly divided into TWO versions of the same destination: 1. A LARGE MAIN PHOTOREALISTIC IMAGE occupying the upper portion of the poster. 2. A MUCH SMALLER SECOND IMAGE centered in the lower portion, rendered as a beautiful watercolor/hand-painted illustration. The lower image must be noticeably smaller than the upper image, with generous cream-colored paper space surrounding it. Do NOT make both images equal in size. UPPER LARGE IMAGE: Show a cinematic golden-hour view of Shanghai from the riverside promenade. Feature the Oriental Pearl Tower prominently, surrounded by Shanghai's modern skyscrapers including Shanghai Tower and the Shanghai World Financial Center. Include the Huangpu River with elegant sightseeing boats and glowing reflections. Add a beautiful traditional Chinese pavilion on one side, a vintage black street lamp, lush greenery, abundant pink cherry blossoms, and a cozy riverside seating area with a wooden chair, soft blanket, coffee cup, travel books, and a camera. Use realistic lighting, detailed architecture, natural reflections, atmospheric sunset clouds, and sophisticated travel-photography aesthetics. LOWER SMALL IMAGE: Create a smaller centered watercolor interpretation of the Shanghai skyline and Huangpu River scene. Reimagine the same landmarks in a soft artistic watercolor style with visible brush textures, delicate color washes, painted cherry blossoms, boats, traditional architecture, and dreamy sky. It should feel like a hand-painted travel postcard rather than a duplicate photograph. Keep this illustration compact and surrounded by plenty of textured cream paper. DESIGN STYLE: Elegant luxury travel magazine meets vintage scrapbook postcard. Warm ivory handmade-paper texture, refined editorial composition, subtle torn-paper edges, delicate floral decorations, vintage postage stamps, Chinese-inspired decorative motifs, thin elegant lines, small travel icons, and tasteful handwritten annotations. TYPOGRAPHY: Large elegant title: "SHANGHAI" Under it: "CHINA" Add a handwritten phrase: "A City of Infinite Possibilities" Add small elegant labels: "MODERN CITY", "RICH CULTURE", "TIMELESS BEAUTY" Near the lower illustration include: "Same City, Different Feelings" Below the small watercolor image, place: "SHANGHAI", "CHINA" Add three small decorative captions: "ICONIC LANDMARKS", "RICH HISTORY", "VIBRANT CULTURE" Add a vintage Shanghai postage stamp with a simplified skyline illustration and subtle Chinese characters. COLOR PALETTE: Soft ivory, sunset peach, warm gold, sky blue, deep navy, natural green, and delicate cherry-blossom pink. The final result should look polished, sophisticated, romantic, premium, highly detailed, and professionally designed. Keep the upper image dominant and large, while the lower watercolor image is clearly smaller and centered with generous negative space around it. Avoid making the two images the same size or creating a simple side-by-side layout.
