Bay at Tregastel Félix Édouard Vallotton (1865-1925)

The picture has something of this: water, ocean, seashore, landscape, beach, sea, island, outdoors, tree, scenic, lake, nature, daylight, sky.
Perhaps it’s a painting of a boat on a beach next to a body of water with a mountain in the distance and a boat in the water in the foreground.
