Viscount Lascelles John Hoppner (1758-1810)

The picture has something of this: people, portrait, coat, wear, woman, jacket, outerwear, lid, necklace, scarf, fur coat, winter, retro, man, poet.
Perhaps it’s a close up of a painting of a man in a red coat with a white shirt and a brown coat over his left shoulder and a tree in the background.
