In my humble opinion you have way too much going on in that signature.

Have to agree with Xstinct, way to much going on, but on a positive note, I like the C4d's used, try blurring and paying around with different techniques for the background to get your depth, with that said after that you should have your self a nice sig. Good Luck, n hope to see more from you!

^^agreed and i would add try to play around with the colors more...use more complimentary so you can make that focal stand out more and also help with the depth. Nice looking effects though!
