Tranquil Pond (Egelsee near Golling, Salzburg) Gustav Klimt (1862-1918)

The picture has something of this: water, tree, outdoors, landscape, park, nature, reflection, leaf, environment, fall, wood, river, pool, daylight, lake.
Perhaps it’s a painting of a body of water with trees in the background and a person standing on the edge of the water with their feet in the water.
