James Raiz is a super-talented artist and a nice guy too.
To debut for sale at last year's TFCon, he made a pair of Gi Joe & Autobots vs Cobra & Decepticons prints, and fans were able to vote for characters on, uh, another website... with a similar name but spelled differently, and with a dotcom. Please don't ban me, I tried to be vague!
He has a youtube channel too on which he posts videos of himself drawing. Here's some time-lapsed vids of both pieces (vids for each character are available too). Watching these prints being drawn sealed the deal for me, and I had to meet him and pick them up.
Uh, it doesn't look like I can embed them in this post, so here's some raw links I guess:
