Pencil sketch

{
  "prompt": "Transform the uploaded image into a highly realistic hand-drawn pencil sketch. Preserve the original proportions, facial features, textures, and fine details exactly as in the source image. Use soft graphite shading, natural line variation, and subtle cross-hatching to create depth and realism. Emphasize accurate light and shadow transitions, clean contours, and lifelike expressions. The final result should resemble a professional artist’s pencil sketch on white drawing paper, with no color, no digital effects, and no exaggeration—purely realistic and natural."
