Landscape with Waterfall, Castle and Peasants Philip James de Loutherbourg (1740-1812)

The picture has something of this: water, outdoors, rock, landscape, nature, mountain, group, tree, river, scenic, daylight, sky, people, geology, recreation.
Perhaps it’s a painting of a waterfall with a castle in the background and a group of people on horseback in the foreground with a waterfall.
