Eugène Emmanuel Amaury-Duval: Portrait of Isaure Chassériau,
Niece of the Artist, Daughter of Théodore Chassériau
While I suppose that technically there's nothing wrong with this painting, personally I don't care for it. There's a very antiseptic feel to it.
There's a page about the young lady in the portrait (in French) with the intriguing title "L'insolite destin d’une bien étrange demoiselle" ("The unusual fate of a strange lady").
