Intercambio de rostro y peinado para retratos de estudio

{
  "Ultra-realistic studio portrait of a young woman in a three-quarter profile pose, head slightly turned toward the camera. She is wearing a black textured blazer over a dark top with minimal accessories, including a small hoop earring. Background is a solid deep red studio backdrop with a smooth gradient. Lighting is soft, diffused studio lighting with gentle shadows and even skin tones. Replace ONLY the face and hairstyle using the reference image. Keep body, pose, clothing, background, lighting, camera angle, framing, and image quality exactly the same. Ensure the new face matches the original head size, angle, and expression with seamless skin blending and natural hair integration. Photorealistic, cinematic quality, sharp focus on eyes, shallow depth of field.",
