I would go with the one you have currently. It's easier to see the wrestlers. The banners, as I Am Slam said, are n00bish. Don't get dishearted though, just piss about with your banners abit more, see what effects the program you use has. Everybody is bad when they start out.
I think both the sigs are not that good looking. Although the one which you are using is better than the one you are asking opinions on. try adding more effects and the font is'nt that good too. My Rate: Ummm... 5/10. for the banner in the sig.
Work On It.
