One of my favorite artist to get something by at conventions is Joe Pekar. This sketch of Firebomb from SENTINELS was done at the 2011 Pittsburgh Comicon and was done in addition to the Rapture pic I posted a while back. Joe is always drawing away at Cons and has a long list. Seeing his work, that's no surprise. His female rendition of characters are always amazing! I also love the way Joe colors and even though it looks like he's using watercolors, this is all done with markers! Please check out more of Joe's work at http://www.joepekar.com/ .
