Homeward Bound John Frederick Herring (1795-1865)

The picture has something of this: cavalry, mammal, seated, people, cowman, animal, group, horse, nature, equestrian, livestock, tree, two, outdoors, motion, rural, farm, dust, man.
Perhaps it’s a painting of a man riding on the back of a brown horse next to a group of brown and white horses in a wooded area with ducks.
