Okay, I admit, I have no 
idea who Blink is. (I know now, though, so I know she's from the X-Men books. Don't worry.) But it's part of the fun of doing convention sketches, when someone comes in with a character you've never heard of. As well as reference, man is reference important. At HeroesCon, if necessary, I could use the insanely useful iPhone to pull some reference off the web. At San Diego, that's not going to be possible, I presume, since I think everyone in the Creative Services and Hollywood has an iPhone, and that's going to slam the 3G network at the San Diego Convention Center.
Back to Blink, though. She was fun to draw. I think this is a definitely different pose, and her skin tone was fun to color since it's not a traditional tone. It made it fun to color.
