I don't quite know how to comment on this one. It's a very long way from perfect but i couldnt tell you at the point whats wrong with the actual sig. The purple is a bit out of place in the top left although i know why you did it. The FX on the left hand are slightly dodgy. You need to turn down the opacity of that C4D. Don't know if this is just me but is it slightly blurry? It, like your other sigs i've seen today, are way too big and you should scrap the text.
