Your sig is good.
Two things though:
1) The signature size limit for this site is 500x150
2) Where did all the brushes and c4d's go?
Apart from that there's nothing wrong with it
I thought you'd used c4d's in it. I was thinking "Wow that lighting effect is awsome... I should get him to make a tut. Oh wait. It's probably some C4D's."
Once again, really, really nice work
