Cheerful Cartoon Character Resembling Curly Hair

Design a cheerful cartoon character resembling a young person with short, curly hair. The character should be wearing a bright green shirt with a collar and long sleeves, paired with light blue pants. Change the footwear to orange sneakers. The character should have a friendly smile and be waving with one hand while the other hand rests casually at their side. The background should be a simple, solid color to keep the focus on the character.
