  "prompt": "Use the uploaded reference image to preserve the subject’s exact facial identity, proportions, hair, and skin tone with zero alteration. Reimagine the portrait as a high-end charcoal and chalk fashion editorial artwork. The subject may be a man or a woman; adapt styling and pose accordingly while maintaining strength, confidence, and elegance. Render the face with highly realistic charcoal detailing—rich blacks, soft greys, and precise facial structure—while highlights on cheekbones, jawline, collarbones, and hair are created using subtle white or warm chalk accents. Clothing is suggested through expressive charcoal strokes and tonal contrast, implying Western luxury silhouettes without detailed textures. Pose is strong and editorial, calm yet commanding. Background is minimal and atmospheric, composed of smudged charcoal gradients or textured paper grain. Lighting is dramatic and directional, sculpting the subject through contrast rather than color. Overall mood is bold, raw, timeless, and powerful—fashion editorial meets fine-art charcoal portrait.",
