Create a digital illustration of a cheerful boy standing in the middle of a bust

Create a digital illustration of a cheerful boy standing in the middle of a bustling city street. He is wearing a loose, oversized light green sweater with cute heart and bear designs on it. His hair is styled in a messy, tousled look. The boy is making a peace sign with both hands and smiling widely. The background should depict a lively urban scene with tall buildings, storefronts, and cars on the road, using pastel colors and light tones. The overall art style should be light and whimsical, with a focus on soft green and pastel hues to match the boy's outfit and the cityscape.
