1st one is kool, like the font. colors are nice also. like what you did with the pixel text 2nd is lamage.
I like your sig style, especially your second one, your first was good alright, but i didnt really like the movie Anyways GREAT sig ^_^ (second)
seems how @pples doesn't have a sig I'll rate the one before him 6/10 it's a nice sig, but make it a .gif so that the transparency matches the background of the forums. Work on that choppy text and you'll have a 8.5/10 IMO
The render in the first one is too blended in to the background, the second sog is better though, 8.5/10 for the second.
