One of my favorite sketches from the 2009 NYC Comic Con has to be this sketch by Christopher Uminga of Wickkid from the 3rd Gen SENTINELS. I love Christopher's style. It's so unique. And he picked the perfect character when he choose to draw Wickkid. On top of all that, Christopher is a super nice guy. I can't recommend him enough, so check out his site at http://www.cuminga.com/ .
