Self Portrait Domenichino (Domenico Zampieri) (1581-1641)

The picture has something of this: portrait, people, man, wear, pensive, music, fashion, business, dark, actor, jacket, facial expression, musician, retro, fine-looking, face, indoors, boy.
Perhaps it’s a close up of a painting of a man in a black shirt with a ring on his left hand and a white collared shirt.
