Create a hyperrealistic full body portrait photograph of a man (the reference image given) seated on the edge of a dark black low rectangular block, leaning slightly forward, one hand gripping his blazer lapel, other hand resting on knee, looking directly at camera with a serious brooding intense expression. He is wearing a full black outfit — black blazer over black button down shirt open at collar, black slim trousers, black tassel loafer shoes, dark luxury watch on wrist. Short styled brown hair, neatly trimmed beard. Background is a dramatic all black architectural studio set with dark geometric shapes, curved arches and rectangular blocks all in matte black, small dark cylindrical vase prop on left side, deep shadow everywhere with single dramatic spotlight on face and torso. Full body visible. Add a small handwritten style signature text "Geminiaiphotoprompt.in" at the bottom left corner of the image. 100% unchanged face no alteration. Image aspect ratio 9:16
