Use the uploaded photo as the only and definitive reference for the person’s face, skin, and hair. Fully replace the original figure with the person from the reference photo, preserving all facial features, proportions, and natural expression exactly as shown — no changes or reinterpretations. 🚫 Do not modify the hair in any way. ✅ Keep the exact same haircut, length, direction, volume, color, and texture as in the uploaded photo — identical in every detail. The hair must remain 100% faithful to the photo: no longer, shorter, restyled, recolored, or volumized variations. 📸 Pose & Composition Girl seated in the center of a high-back armchair.
