This certainly looks good. It looks like something from MindChamber. I love the TV sets on his arm. That's what they are, right? I'd love to see a video game with this character. Again, it seems like it would be a MindChamber game.
Maybe you could have used a background. This was pretty good for something short. It's sad when the random ones on the Portal are larger. I like his tail too. It kind of looks like a demonic one.
