This sketch of Spike from the 1st Gen SENTINELS was drawn by Scott Derby at the 2009 Pittsburgh Comic Con. Scott is a really cool guy who I've gotten to know over the last few years at conventions. He has a unique style that I really like, it's kind of a combination of animation and silk screen. His prints are amazing and he's always selling a ton of them. I let him choose to draw whoever he wanted and he picked Spike. He must have secretly loved the mullet. Check out more of his work at http://www.scottderby.blogspot.com/ . Tell him the angry guy sent ya! lol.
