Urbanes Skizzieren mit kräftigem Akzentstil

Transform this image into an urban sketch illustration with a bold color accent. Use loose, expressive black ink lines to outline the scene as if drawn quickly on location. Keep the perspective informal and spontaneous, with some lines slightly irregular or suggestive. Leave large areas of the background white or unshaded. Highlight just one object - such as a café awning, a car, or a streetlight - using soft watercolor or marker in a single vibrant color. The overall mood should feel observational, lively, and authentic, like a travel sketchbook page capturing a real moment in the city.
