A realistic graphite pencil portrait of [a young Black man] drawn on off-white textured paper. Chest-up three-quarter view, head turned slightly to the viewer's left while his eyes look calmly toward the viewer's right. Natural facial proportions with a composed, serious expression, closely cropped textured black hair, smooth skin rendered in rich grayscale tonal values, subtle facial hair along the jaw, and thin rectangular metal eyeglasses with transparent lenses. He wears [a light collared dress shirt with a dark necktie]. Classical hand-drawn graphite technique with visible hatching, crosshatching, soft blending, and fine tonal shading. Minimal background with faint diagonal pencil strokes. Monochromatic grayscale, no color, no text, resembling a fine art sketch scanned on paper.
