The first one I see some neon holes in the guy's neck.
Probably from over doing an effect.
Try removing the text on all of them because text is a hard thing to work with and can ruin a whole signature.
Stick with the plain image for now.
So....I say 5/10.
Good work for the most part though.
Edit: Also, it would also look a little better with a small:
2px or 1px border around the signature
