I know its a little big but i won't be using it on forums right now.

lol well you may not be using that one but your current one seems just as big :P and man is it big :)

Anyway forgeting how big it is, your brushings is done well, I thin you stuck to many tech brushes in the bottom left conner. On half of you tech brushes you should lower their opacity or set them to soft light or even overlay.

Text could actually work except everything on your sig is thin and it's think.

Your current sig is too huge too...

-too much red doesn't make the sig appealing
-too big in dimensions of course..
-font colour is too bland
-tech brushes are just white, maybe if they blended they might look better
-too many random tech brushes too
