Dude no offense to you but they are pretty crappy the bg is just the clouds filter with you just changing the colors. Then you can still even see the bg or the render. So in all I only give it a 2/10
That looks like a bannner, not a sig. Make it smaller. If you put that on an admin will see it and think that you're advertising. That would get you a ban.
2/10.
[EDIT]: Wtf noob. You just changed it.
Put this exact line in your sig if you hate niggers
