Create a stunning 3D illustration depicting an urban landscape at dawn, enveloped in a thick layer of fog that softens the outlines of buildings and streets. The scene should feature a city skyline with a mix of modern skyscrapers and classic architecture, rendered in realistic textures that highlight the interplay of light and shadow. The fog should be illustrated with volumetric effects, creating a sense of depth and atmosphere as it rolls through the streets and around the structures. Incorporate warm hues of dawn—soft oranges, pinks, and yellows—illuminating the fog and casting a gentle glow on the buildings. Add subtle details like streetlights flickering to life and silhouettes of early morning commuters, enhancing the sense of movement and life in the city. The overall composition should evoke a feeling of tranquility and awakening, inviting viewers to experience the beauty of urban fog at dawn.
