Lighthouse on a City Tower: Cartoon Beacon Above

Cartoon-style illustration of a whimsical lighthouse perched atop the roof garden of a towering skyscraper in a lively city. Bold black outlines, bright flat colors, and simplified shapes. The lighthouse is red-and-white striped with a glowing lantern room at the top, casting a wide, friendly beam across a pastel sunset sky. The rooftop garden features potted plants, a tiny bench, and wind chimes; the glassy skyscraper reflects neon city lights. In the background, other stylized buildings with cheerful windows create a playful urban landscape. Atmosphere: cheerful, adventurous, dreamlike; perspective from slightly below to emphasize height.
