Portrait 3:4 digital photographic portrait constructed through a fine regular square lattice of luminous circular dots on almost black. A young adult man's head and neck occupy x35–82%, y14–84%, with short dark hair, lowered gaze and face turned slightly toward left. Keep the left half of face near-black, with just sparse blue dot contours; the right forehead, cheek and neck carry warm peach and coral-orange illuminated dots, pale blue dots intermixed. Visible right ear near x77%,y37%; mouth near x51%,y62%. The portrait stops at a black crew-neck collar around y83%. Hair and shoulder boundaries dissolve into sparse isolated blue/orange pixels, especially around top and right. Dot diameter is about0.5% width with consistent spacing, much smaller than a pop-art halftone pattern. Preserve realistic facial anatomy beneath the grid, narrow hard nose shadow, solid black eye socket and mouth shadow. Outer field contains very sparse irregular blue/coral points with ample black negative space. Slight analog grain, crisp dots, no glow fog.
Negative prompt
No smooth undotted portrait, no giant circles, no full frontal symmetric face, no smile, no bright background, no flat cartoon, no text. Preserve dark left half rather than adding fill light.
