Ok this looks a lot better, so first off all, good job, u have improved
1 ur size is smaller wich makes it look more pro
2 the effect u use is more plain wich makes the sig easier for the eye
3 u can actually read your name now
4 it's monotone, 1/2 color very important with sigs
5 border
a few things, u might want to put a blue color or hue layer about the blue version too it seems like that is the original and the only one who has ur name with another color glow then the rest of the sigs, also u might want to try and work on your backgrounds, just a tought, they are simple now, and it's an improvement on your last, but if u want to become better, u might want to take that as an advice. Also your sig was kinda full allready, but u put even more txt on it (the random numbers), doesn't look very good, also, when ur using random numbers, try to kep the opacity down. Also ur sig is mostly information, I don't know where u want to go with ur sigs, but if u want to be them more an artwork then a source for info (wich can be under your sig too) then tro to make it more intresting to look at, some characters or light fx, flashy effects etc.
