拟真铅笔素描肖像

A highly structured JSON prompt for generating a monochromatic, hyper-realistic pencil sketch portrait (digital illustration) based on a reference image. It specifies detailed visual attributes, micro-details (wisps of hair, catchlights in eyes), composition (close-up, shallow depth of field), and lighting (soft, diffused studio lighting) to mimic a professional drawing.
