Create an ultra-detailed, realistic black-and-white colouring book illustration of a beautiful modern city street on a rainy day. Use professional architectural line art with crisp, clean, high-resolution black outlines on a pure white background. Foreground: A cheerful young girl wearing a raincoat, backpack and rain boots walks along a wet pavement, holding a large umbrella. A cute, fluffy dog walks beside her on a leash. Include a charming café storefront with large glass windows, striped awnings, outdoor tables and chairs, potted plants, and a chalkboard displaying a coffee cup. Middle ground: A busy urban street filled with realistic cars, a detailed city bus, pedestrians carrying umbrellas, ornate vintage street lamps, bollards, pavement tiles, road markings and numerous puddles. Background: Tall modern skyscrapers blend with a magnificent historic European-style building featuring a grand clock tower, decorative domes, arched windows, balconies and intricate architectural details. Include leafy street trees and additional buildings fading into the distance. Rainy atmosphere: Clearly defined raindrops and diagonal rain streaks, water ripples in puddles, realistic reflections of buildings, vehicles and streetlights on the wet road. Capture the cosy, cinematic feeling of a rainy city afternoon.
