It's a copy of this artist I just discovered: Pascal-Adolphe-JeanDagnan-Bouveret. I'm surprised I hadn't heard of him before. Really good stuff.
So I translated his oil painting into watercolor, but the paper buckled and apparently didn't like wet media very much, so I had to cheat and use pen for the black. I wanted to paint her whole body but with the way the paper reacted... it wouldn't have gone well. This thing is teeny tiny and will remain indefinitely unfinished.
