Illustration Artwork

The main person from the provided photo, with face, features, skin texture and expression fully preserved so it is clearly the same person; change only the hairstyle to a playful short bob.

Keep the person's head pose, body posture and worn clothing unchanged; same framing as the original.

The original photo's lighting conditions must remain unchanged; the new hair's texture, sheen and shadows blend perfectly with the original lighting; optimization idea: switch the light direction (left to right) for a different mood.

The person's existing background and environment must remain exactly as in the original photo, with no changes.

Highly photorealistic, seamless blending; the new hair intelligently adjusted to head shape, face shape and on-scene lighting.

Identity preservation, background unchanged, body posture unchanged, seamless integration; female hairstyle references include long straight hair, romantic large waves, playful short bob, elegant French bangs with shoulder-length hair, refined vintage updo, sharp pixie cut, fluffy wool curls, high ponytail, dreadlocks, silver-gray gradient long hair; male references include classic business slick-back, textured short cut/quiff, clean buzz cut, retro center-part, fluffy Korean perm, casual shoulder-length hair, undercut, mohawk, samurai bun; chosen here is the playful short bob.
