When you told me on MSN you didn't use C4Ds, I was like, "WTF." Anyways, generally, I like it. The stock is extremely hard to see under the effects and all, so could you lay off the effects on him a bit? I think you could extend the overall effects both left and right just a little bit more, so it doesn't look like a sphere, unless it was intentional. I think the tag could use a blue cooling filter, but overall...yeah.
Actually, I added the stock for like 5 more layers because you couldn't see it, and it's the most visible thing because everything draws into it, and it isn't very abstracted. It was intentional. Already done dat D: .
You should probably add more apparent-depth to it. As well as flow. Bring out the stock more as well. Otherwise it's pretty good.
It's pretty sweet, but like Raito said the effects on the stock seem a little overdone. Nice going TBK. ;D
