Aw! I like the expression in the eyes and the overall composition. Really good color choices too, she reminds me of the Diablo sorceress a lot. Something's off around the mouth though. Is that her lower lip? Is her tongue sticking out? The presence of the line beneath her mouth makes it looks like the lower lip's line. I think a bit more clarification around that area could add more personality and expression to the portrait. I think a bit more contrast and highlighting could make the portrait itself look slightly more memorable.
