Create an anime-style illustration of a cheerful boy in a bustling cityscape. The perspective should be from a low angle, making the subject appear towering and dynamic. The boy is wearing a bright red sweater, gray shorts, and red sneakers. He has a happy expression, with his arm raised in excitement. The background features tall buildings with billboards and advertisements, resembling a vibrant urban setting. The sky is clear with a few clouds, adding to the lively atmosphere.
