I think I mentioned before I had sketched a few of these cards out for one of my classes as a demonstration of quick head sketches. I'm not sure I mentioned I let my students choose which characters I drew. In this case it's Jubilee; former mutant, current vampire.
An aside: I managed to snag the first issue of Kathryn Immonen & Phil Noto's mini-series about Wolverine and Jubilee and it was really, really good. I missed the second so I'm going to trade-wait now, but thought I should plug a well-written and drawn book.
