铅笔素描肖像

Draw the person or subject described in the user request as a hand-made graphite pencil portrait on off-white textured drawing paper. If a reference photo is uploaded, translate its likeness faithfully into the drawing; otherwise build the face from the description. Use traditional draftsmanship throughout: confident construction lines, fine cross-hatching, soft charcoal blending and realistic grayscale tonal values that model skin, hair, fabric and small details like glasses or jewelry with museum-grade care. Frame a chest-up, three-quarter portrait by default, head gently turned with a calm, composed expression, and follow any pose or crop the request describes instead. Keep the shading around the eyes, nose, lips and collar especially delicate so the piece reads as patient handwork, never a photo filter. Leave the background minimal — faint diagonal pencil strokes on clean paper — unless the user asks for the editorial variant, in which case place one bold, flat geometric shape of saturated color behind the figure for an indie-magazine contrast. The finished image should look like a real drawing photographed on paper. No color on the figure itself, no text, no watermark. User request: a young man in glasses, shirt and tie, chest-up three-quarter view
