Vintage Pencil Portrait Transformation

Using the provided reference image, transform the portrait into a hand-drawn vintage graphite fashion sketch while preserving the exact subject identity, pose, expression, hairstyle, outfit, hat, accessories, and overall framing. Convert the photo into monochrome pencil-and-charcoal line art on warm aged beige paper, with visible cross-hatching, loose sketch outlines, textured shading, smudged graphite shadows, and slightly rough unfinished edges around the hair, hat, shoulders, and sweater. Keep the same bust-up composition and finger-to-lips gesture, but remove photorealistic color and replace it with subtle sepia-gray tones and paper grain. Emphasize detailed pencil texture in the knitted beanie, hair strands, facial features, hand, and patterned sweater. Maintain the reference’s simple background as blank vintage paper with no added objects, text, border, or watermark.
