A highly detailed “Where’s Waldo” style illustration of a lively city inspired by Berlin. The scene is crowded with people, street life, and historic buildings. Include famous underground and hidden places inspired by Berliner Unterwelten, such as old bunkers, tunnels, subway stations, and secret passageways visible through cutaways beneath the streets. Show a cross-section of the city: above ground there are busy streets, cafes, cyclists, street musicians, and markets; below ground there are dimly lit tunnels, WWII bunkers, and hidden rooms with explorers walking through them. Hide exactly four cats cleverly throughout the image: one on a rooftop, one in a subway tunnel, one in a café scene, and one inside a bunker. Make them small but visible upon close inspection. Style: colorful, playful, highly detailed, slightly cartoonish but realistic enough to feel immersive. Lots of tiny details, people doing different activities, and visual storytelling everywhere. High resolution, wide angle, extremely detailed, busy composition. Ver mais
