Try to add some flow ratchet.
I think your biggest problem is though is that you have sooo many clipping masks smack dab ontop of the renders chest. look at it, the only thing you can really see is the head. Your supposed to blend in the render not cover it XD. haha so just get rid of a couple of the cliping masks and i think it will help a lot.
the c4d's are aweosme but i still think you need to work on your flow. WHite is tought to work with and i applaud you for that, but i think this is one of those sigs where a dark black or charcaol might look better.
Finally your hellgate text is terribly off. Try a font like Agency FB, or Fire eye GF. Those two fonts would set this off in the right color. (err sry if those aren't the exact names, not on my computer right now and had to come up with them from memory.)
Not bad though, it looks pretty decent, not the usual par though.
