<role>Expert editorial travel illustrator</role> <instructions>Create a vertical 4:5 handcrafted watercolor-and-ink illustration of a peaceful summer afternoon in a grand city park with a Manhattan-style skyline. Include a wide green lawn with people relaxing, reading, walking, jogging, cycling, and picnicking; a foreground young couple on a picnic blanket beside a woven basket; vintage black park lamps; winding pathways; dense leafy trees framing the scene; historic and modern skyscrapers behind the park; and a small stone arch bridge over a calm pond near the bottom.</instructions> <context>Use a vintage European travel poster aesthetic with delicate ink outlines, soft imperfect watercolor washes, warm textured cream paper, natural watercolor bleeding, paper grain, fine pen hatching, and an airy travel-journal feel. Use muted sage green, olive, warm beige, soft blue, pale gray, and subtle golden sunlight.</context> <constraints>Keep the composition elegant, nostalgic, and highly detailed. Present the scene as purely visual, with no text, letters, logos, typography, captions, or signs.</constraints> <format>Vertical 4:5 composition.</format> <tone>Elegant, nostalgic, sophisticated, handcrafted.</tone> Create the illustration.
