A Lady as a Shepherdess, John Greenhill
On Google Art Project, also downloadable high-res from Wikimedia Commons. Original is in the Dulwich Picture Gallery.
Though she is well presented, I don’t think Greenhhill has gone out of his way to flatter the sitter — or the sheep.

It is surprising how computer screen flattens these types of multi-layered paintings. Looks boring and almost without colour but look at it in person and it will come alive.
