He wanted C&C.
Anyway, I agree with everything Juo said. You should look up tutorials on planet renders. And the basic size for sigs is something on the lines of 350-400px width x 120-140px height. Or something along those lines. Biggest complaint is the text. Your name really doesn't matter, no one really cares who made it, just if it looks nice or not. So make your text small, if not hidden. Not OMFGIMAEDTHISSIGISNTITKOOLLOL. Alright?
Good Example (I think anyway o.o):
^ I think this is a good example of when Big text versus small text is important. See how when you look at the picture, your eyes sorta automatically go to the center because of the text. That's the "focal" point, most important part of the signature. I'm gonna guess you wanted your focal to be your tori, but when I look at your sig, I see your big letters first. Also, in this sig, you see how I made the less important text a little smaller and darker? Might wanna try that when your putting your name in the sig. Unless your name is the focal of course. Oke dokey?
Keep at it, we all got our start at some point right xD.
