IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while applying the post-yoga transformation. Maintain complete facial likeness and identity recognition.

TRANSFORMATION DESCRIPTION: Transform the subject to appear as if they have just completed a rejuvenating yoga session. Apply a natural, healthy post-exercise glow to the skin. Create a serene, peaceful, and centered facial expression with slightly relaxed facial muscles and a gentle, content smile. The eyes should reflect calmness and inner peace. Add subtle, natural-looking sheen on the forehead and cheeks to simulate light perspiration from a workout. The overall appearance should be revitalized, refreshed, and spiritually centered.
