The border kinda makes it look awkward. But i like the text and I like the effects. But more color! I like t3h colors and i do not see many in your signatures!
Add color There wasnt any color in either of the picures i used for my current. (aside from white) and i added a little bit here and thurr. Notihng fancy shmancy. Just a touch somewhere. That's just me though. I love your concepts.
