Portrait of Sergey Savvich Yakovlev Vladimir Borovikovsky (1757-1825)

The picture has something of this: people, portrait, wear, man, music, two, administration, woman, leader, facial expression, outerwear, jacket, outfit, royalty, side view, profile.
Perhaps it’s a painting of a man sitting at a desk with a book in his lap and a ring on his left hand and a red curtain in the background.
