Create a surreal artwork depicting a cityscape enveloped in thick fog, where the buildings appear to float above the ground, defying gravity. The scene should be bathed in a soft, ethereal light that filters through the fog, casting long shadows and creating a dreamlike atmosphere. Incorporate whimsical elements such as oversized clocks melting over the edges of skyscrapers and trees with luminous leaves that glow faintly in the mist. The color palette should consist of muted pastels and deep blues, enhancing the otherworldly feel. The composition should draw the viewer's eye through layers of fog and surreal objects, inviting them to explore this enchanting urban landscape.
