扁平矢量头像

Design a clean, front-facing flat-vector avatar of the person or character described in the user request, or modeled on the uploaded reference photo while keeping the likeness friendly and recognizable. Center the portrait and crop from the upper chest up so the subject fills most of a square 1:1 frame in a balanced, symmetrical composition. Build the face, hair, and clothing from bold geometric forms with crisp edges and smooth flat color fills, using only subtle soft shadows for depth — simplified yet expressive features with clear eyes, tidy hair shapes, and natural, warm skin tones. Keep detail minimal and deliberate: no photorealistic texture, no heavy gradients, no busy accessories beyond what the request specifies. Place the subject against a single solid, vivid background color with no patterns or objects, chosen to complement the portrait's palette; default to a warm saturated tone when none is specified. The finished avatar should feel polished and contemporary, reading clearly at both large and thumbnail sizes as a professional or social profile icon. Do not add text, watermarks, logos, borders, or extra characters. User request: curly black hair, round gold glasses, mustard sweater, teal background
