The Sleeping Gypsy Henri Julien Felix Rousseau (1844-1910)

The picture has something of this: people, mammal, dog, woman, competition, girl, child, water, two, reclining, recreation, indoors, canine, side view, fun, portrait, animal.
Perhaps it’s a painting of a lion standing next to a man laying on a bed with a guitar in front of him and a full moon in the background.
