Refer to the uploaded image and transform the portrait photo into a minimalist and trendy 3D cartoon character. Adopt a chibi full-body or half-body doll proportion, with a large head and small body. The character should be positioned in the center of the frame, standing upright, exuding a cold and lazy aura. The expression should be slightly world-weary, with drooping eyelids, relaxed gaze, straight mouth, round and plump face, small nose, and delicate, soft skin. The character should wear a light gray knitted cap and exaggerated black large headphones, with a small amount of bangs showing. The clothing should be a pure-colored loose knitted top with a simple design, natural draping, and unified and refreshing color scheme. The character design should have a trendy doll-like feel and an animated short film character vibe. The 3D modeling should be exquisite, with soft and delicate materials, clear knitting texture. The headphones should have a realistic plastic and frosted texture, with soft and even lighting. The background should be a high-saturation pure-color gradient background, with a clean and simple image, highlighting the main character. The overall visual should be cute, high-end, and fashionable, with a strong avatar and IP character feel. The output ratio is 1:1
