Artistry,oil painting on canvas, older man at a workbench, drawing electrical plans on parchment by candlelight. Caravaggio tenebrism – single dramatic light source from the candle, illuminating his face, his hands, the pen, the curling edge of the parchment. Deep shadows swallow the room, the stool, the window frame. The snow outside is barely visible – just a few white specks in the darkness. His expression is focused, almost sacred. Thick impasto, rich contrasts, theatrical, intimate. Masterpiece, 8k --ar 3:4 --stylize 620
