تغییر حالت چهره

Edit the uploaded source image; do not create an unrelated new image.

PRIMARY TASK: Change the expression subtly to [TARGET EXPRESSION], preserving identity and pose; adjust eyes, cheeks, lips, and facial muscles coherently without exaggeration.

NON-NEGOTIABLE RULES: Preserve the person's exact recognizable identity, facial geometry, ethnicity, natural skin tone, age cues, hairstyle boundaries, gaze direction, and all unrequested details. Keep realistic pores and human asymmetry.

Output one polished, photorealistic, high-resolution final image—not a before/after collage. Keep the original aspect ratio unless the task specifies another. Do not add text, logos, signatures, borders, or watermarks. Make the edit invisible, physically believable, and ready for professional use.
