Portrait of poet and playwright Alexander Petrovich Sumarokov Anton Losenko (1737-1773)

The picture has something of this: portrait, people, wear, woman, man, music, model, light, musician, facial expression, jewelry, fashion, outerwear, singer, girl, jacket.
Perhaps it’s a close up of a painting of a person wearing a black coat and a white shirt and holding a piece of paper in front of his left hand.
