Georges Seurat – Study for Bathers at Asnieres Part 3 National Gallery UK

The picture has something of this: water, people, Impressionism, man, swimming, wear, dug-out pool, recreation, splash, swimmer, woman, shot, pastel, nude, child.
Perhaps it’s a painting of a group of people standing next to each other in front of a body of water with one person in the foreground of the painting.
