I've seen the original, so would have most people, so i must admit i love the eye colour change, it's brilliantly done, and looks amazing. Too bad thats the only good thing about the signature, the render needs to be smaller. I don't even know what the background is. The text is a good idea with the colours, too bad it can't be pulled off with this sig, the font is horrible and it's placed wrong.
Imo make the render smaller, add a grungestract background, and sort out the text, this could be a killer sig, if you work on it.
