Vintage Porträtskizze in Graphit und Kohle

Transform the reference photo into a vintage hand-drawn graphite and charcoal bust sketch on [warm aged beige] textured paper. Preserve the exact identity, facial expression, pose, framing, hairstyle, beanie, hair clips, sweater, and accessories from the reference photo. Render as a [highly detailed realistic graphite portrait] with [rough expressive pencil and charcoal strokes], visible construction lines, crosshatching, and soft smudged shading. Detail fine hair strands and knitted fabric texture, leaving unfinished, loose sketch edges around the shoulders. Centered composition on a clean paper background with subtle sepia warmth, free of text, borders, or watermarks.
