Isometric diorama of a playground scene featuring a vibrant, colorful jungle gym right in the middle of a busy city street. Surrounding the jungle gym are various playground structures and kids playing, with cars and pedestrians in the background to depict urban life. The jungle gym stands out with bright colors like red, yellow, blue, and green, contrasting against the vintage tones of the cityscape. 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
