Vintage Travel Poster of Istanbul

Create a vertically composed vintage travel poster of Istanbul, Türkiye, divided naturally into two connected scenic sections, one above the other, on textured cream watercolor paper. TOP SECTION: Show the iconic Istanbul skyline at golden sunset, featuring a magnificent historic domed mosque with elegant slender minarets overlooking the Bosphorus. Include several ferries crossing the water, glowing reflections, waterfront buildings, trees, distant city silhouettes, and flying seagulls. Use warm sunset colors with blue, peach, and golden watercolor washes. BOTTOM SECTION: Show a charming narrow cobblestone street descending toward the Bosphorus, surrounded by beautiful historic Ottoman-style buildings, colorful flower-covered balconies, bougainvillea, warm vintage lanterns, teal doors, small café tables and chairs, potted plants, and a cozy “CAFÉ” sign. The Istanbul skyline and Bosphorus should remain visible in the distance. Use delicate fine-ink architectural linework, hand-painted watercolor textures, subtle paint splashes, paper grain, artistic imperfections, soft reflections, and elegant vintage travel-poster composition. Add tasteful typography: “ISTANBUL” “TÜRKİYE” “Travel Explore Discover” Include a small compass rose and subtle hand-drawn map/sketch elements. The final artwork should look like a professionally illustrated vintage travel postcard made by a skilled watercolor artist, highly detailed, elegant, nostalgic, artistic, and premium. Avoid photorealism, 3D rendering, modern digital graphics, and cartoon styling.
