The Brook of Les Puits-Noir Gustave Courbet (1819-1877)

The picture has something of this: tree, wood, nature, water, landscape, river, leaf, light, fog, fall, reflection, outdoors, dawn, lake, mist, park, rock, sun, lush.
Perhaps it’s a painting of a stream in a wooded area with a horse in the foreground and a man on the far side of the stream in the background.
