Isometric diorama of a playground scene featuring a vibrant, colorful jungle gym right in the middle of a busy city street filled with tall, gray skyscrapers. Surrounding the jungle gym are various playground structures and kids playing, while the background showcases the imposing, monochromatic buildings of the urban landscape. The jungle gym stands out with bright colors like red, yellow, blue, and green, creating a striking contrast against the gray tones of the city. The scene should have a cute, whimsical aesthetic, rendered in extremely high quality with well-lit details, as if created in Unreal Engine. 4K, high resolution, --ar 16:9
