an ORDINARY Korean woman in her early sixties — explicitly NOT a fashion model, NOT idealised, NOT a beauty-standard face. A real individual Korean face: slightly asymmetric features, visible skin texture and pores, a facial structure that is clearly distinct from other people. She is a swimming instructor at an indoor pool. She looks approachable and well-groomed, but ordinary. Very short practical grey hair, a zipped-up long-sleeve navy sports jacket buttoned to the collarbone, a whistle lanyard. Cool blue-green light bouncing up from the pool water onto her face, plus overhead hall lights; the blurred background is an indoor swimming pool hall with no other people in frame. Confident, hands not in frame, a firm closed-mouth smile. Square 1:1 social-media profile photo, photorealistic candid portrait photograph. FRAMING (strict): the crop ends at the middle of the chest — nothing below the chest is in frame. The head, the neck and BOTH shoulders are all fully inside the frame, with a small margin of empty space above the hair. The subject fills most of the frame and is centred. The background is visible but softly out of focus. Normal healthy human anatomy: head, neck and shoulders all clearly present and correctly proportioned. NORMAL neck proportions, not elongated. Two normal hands are NOT required in frame; no extra limbs, no distorted fingers. FULLY CLOTHED in a long-sleeve sports jacket covering shoulders, chest and arms. NOT swimwear. No other people in the frame. No text, no letters, no numbers, no signage, no logo and no watermark anywhere in the image. Do NOT include any real company logo, real brand name or real trademark.
