I thought David Hovey did a great job with some of the character art (Dr. Emanuel Ashbel, Jose Morales); Mirco Paganessi knocked it out of the park with Fetch; David Hueso with Quaterman and Teleportation Device, Recardo Rullo and Matthew Sweeney with everything they did; Michele Frigo did an amazing job with Incubation... I'm sure I could think of more, but those are ones that immediately come to mind.
