Stroke sketch

"A detailed hand-drawn portrait of a man with short dark hair and light stubble, wearing round red-tinted glasses and a red jacket with a raised collar. The artwork is in a sketchy, cross-hatched ink style with rough pencil lines and expressive strokes. The background features abstract geometric construction lines, circles, and architectural drafting marks, giving a technical/artistic fusion look. 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.
