Well, here are the two I made today. I had a lot of fun making the Kofi Kingston sig in particular because of the Spiderman reference.
I like the coloring on the Brock one. It really works into the sig.
The Kofi one is a cool idea but the color choice is meh. Since everyone uses green in Kofi sigs you should go the other way and try blue or something. Orange would fit him too.
Just my two cents.
