Design a vibrant mixed media artwork depicting a foggy street scene in a city. The composition should include a combination of painted elements and collage materials, such as newspaper clippings and fabric swatches, to create a rich, textured effect. Use bold colors for the streetlights and storefronts, contrasting with the soft, gray tones of the fog that envelops the scene. Incorporate playful details like a cat peeking out from behind a lamppost and pedestrians with colorful raincoats, their features stylized and exaggerated. The layering of materials should create a sense of depth, with the fog acting as a unifying element that ties the various components together. This artwork should convey the charm and vibrancy of city life, even in the midst of fog.
