A high-quality digital illustration in a caricature style, featuring with exaggerated features, a big smile showing teeth, and light teal green eyeglasses. Include stylized cross-hatching shadows on the face and neck. The background must be clean and white, decorated with black whimsical hand-drawn line-art doodles, swirls, and dynamic motion effects. The character should be wearing a olive-green t-shirt with a sketch-like texture, with the overall style being a hand-drawn, energetic cartoon portrait.
