Transform the uploaded portrait into a realistic teenage version of the same person, around 15-18 years old. Preserve identity first: keep the same face structure, eyes, nose, lips, expression, pose, hairstyle direction, clothing, background, lighting, camera angle, and overall composition. Make the person look naturally younger by reducing wrinkles, fine lines, eye bags, age spots, beard/stubble if present, and mature facial heaviness. Add subtle teenage softness: smoother but realistic skin, fuller cheeks, softer jawline, fresher eyes, and a youthful facial balance. Do not change gender, ethnicity, body shape, outfit, accessories, background, or the number of people. Do not create a different person. Do not over-beautify, add heavy makeup, make the face plastic, cartoonish, doll-like, or too childlike. Do not make the subject look under 15. Avoid nudity, sexualization, suggestive styling, or revealing clothing. Output a photorealistic, natural, high-quality teenage portrait that still clearly looks like the uploaded person.
