Create a mixed media collage that captures the essence of a foggy urban landscape. The artwork should feature a layered composition, combining photographs of city buildings with textured paper and fabric to represent the fog. Use soft, muted colors to evoke the atmosphere of a misty morning, allowing the fog to blend seamlessly with the urban elements. Incorporate cut-out figures of people walking with umbrellas, their silhouettes partially obscured by the fog, adding a sense of movement and life to the scene. The background should include a skyline that fades into the fog, creating depth and intrigue. This collage should invite viewers to explore the interplay of textures and layers, evoking a sense of mystery and tranquility in the city.
