Small help with Signature.

[HypnoticX07]

As you can see i tried to make my own signature, with paint.net. This is MY FIRST time. But my problem is i can't seem to get rid of the background. I just want it like everyone elses sigs. I'm kinda of a newb at this stuff, so any kind of help would be appreciated. .

~Thanks , HypnoticX07
