Portrait of Isaure Chassériau (1838)

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").
