  "target_image": "[the reference photo]",
  "prompt": "Preserve the facial identity, proportions, hair, and skin tone from the reference photo without alteration, reimagining the portrait as a high-end charcoal and chalk fashion editorial artwork. Adapt styling and pose while maintaining strength, confidence, and elegance. Render the face with realistic charcoal detailing—rich blacks, soft greys, and precise bone structure—accented with subtle white or warm chalk highlights on cheekbones, jawline, collarbones, and hair. Depict clothing with expressive charcoal strokes and tonal contrast implying luxury tailored silhouettes. Editorial, calm yet commanding pose. Minimal atmospheric background of smudged charcoal gradients and textured paper grain. Dramatic directional lighting sculpting the subject through pure tonal contrast. Timeless, bold fine-art fashion portrait.",
