Hetty Sorrel John Collier (1850-1934)

The picture has something of this: woman, people, dress, fall, tree, girl, outdoors, portrait, wear, nature, fashion, nymph, park, model, child, wood, hair.
Perhaps it’s a painting of a woman in a blue dress with a red shawl on her head standing in a wooded area with rocks and a tree in the background.
