The picture has something of this: mammal, cattle, cavalry, livestock, cow, landscape, dawn, agriculture, sunset, tree, outdoors, farm, pastoral, fog, grass, sheep, grassland, countryside, nature.
Perhaps it’s a painting of a group of cows grazing in a field next to a wooded area with a house in the distance and a person on a bicycle.
