young Italian. 1831-36 Orest Adamovich Kiprensky (1782-1836)

The picture has something of this: people, man, wear, lid, military, soldier, weapon, portrait, veil, war, uniform, retro, army, gun.
Perhaps it’s a painting of a man with a hat and boots standing in the middle of a field with his hands in his pockets and a hat on his head.
