Here's one of 
the sketches I did at HeroesCon. I grabbed a snap of it on my now-sadly-outddated iPhone. I messed with the levels in Photoshop and converted it to a blueline so I could reprint it on bristol and ink it again. It's a nice way to save sketches when you can't get a scan per se. And then I have another original to sell, too. How cool is that?
This one is of the Black Cat, created by Marv Wolfman for the Spider-Man books. She hasn't made an appearance in Powerful Women yet (unlike Poison Ivy, who seems to command at least a page a volume), so it's always good to see someone new in those pages.
