Portrait of Ivan Lopukhin Dmitry Levitsky (Levitzky) (1735-1822)

The picture has something of this: portrait, people, wear, man, music, tattoo, jacket, retro, costume, musician, vintage, sword, singer, facial expression, mustache.
Perhaps it’s a close up of a painting of a man in a red uniform with a gold medal on his left shoulder and a blue sky in the background.
