若年ポートレートの自然なシニア変化

Create a realistic age progression of the uploaded young adult to approximately age 75. Preserve the subject’s exact identity, eye shape, nose, smile, facial bone structure, skin tone, seated pose, body type, denim outfit, park bench, framing and camera angle. Add natural gray thinning hair, age-appropriate wrinkles, subtle facial volume loss, mature hands and believable healthy aging under warm late-afternoon light. Update all visible skin consistently without turning the result into a caricature. Do not make the subject ill or frail, change ethnicity, add extreme spots, alter the background or generate a different relative.
