Reclining female Nude in a Landscape William Etty (1787-1849)

The picture has something of this: nude, people, water, man, portrait, shirtless, woman, dark, light, wet, strength, girl, recreation, rock, cave, ocean.
Perhaps it’s a painting of a naked woman sitting on a rock next to a body of water in a wooded area, with trees and bushes in the background.
