Gwen John I found this painting "Self-Portrait (1902)" by Welsh painter and one-time student of Whistler's  Gwendolen John on Wikipedia.  I have been to the Tate a few times but don't remember this painting.  The technique isn't exquisite  or anything, but I love the introspective feeling of the painting.  I like the green and red color combination in particular.  Both the models I'm using right now are red-headed, so I might try a similar color combination on one of my paintings.
