Vintage Graphite Pencil Sketch Portrait

“Transform the reference photo into a detailed monochrome graphite pencil sketch. Preserve the subject’s pose, facial features, clothing, proportions, and composition. Use realistic pencil strokes, fine cross-hatching, natural shading, textured details, and subtle highlights. Keep the subject highly detailed while making the background slightly softer and sketchier. Create an authentic hand-drawn graphite-on-paper appearance with a vintage artistic feel, no color, no digital-looking effects.” Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
