Sketch Cards

Here are two sketch cards I did for a cancer benefit. I'm not quite sure if these will be auctioned off or sold in bundles but either way it's for a great cause. This is Batgirl (DC) and Black Cat (Marvel) I'm looking forward to doing more sketch cards, I really like working on them a lot. I also did a set of 2 Starwars cards but I didn't scan them. Hopefully I'll be able to find a way to post them up as well.
I hope you like what I've done!
