Jens Juel (1745-1802) – Running boy. Marcus Holst von Schmidten Kobenhavn (SMK) National Gallery of Denmark

The picture has something of this: girl, people, woman, portrait, model, wear, fashion, recreation, nude, motion, brunette, outdoors, dress, man, light, glamour, landscape, sexy.
Perhaps it’s a painting of a young boy in a brown suit and white shirt, holding a hat and carrying a bag, in a wooded area with trees and a house in the background.
