Cool man! Seriosly you improved alot, i might even request a signature from you someday.
Now abouth the signature: the effects are just awesome, the render maches with the backgrownd, you have a spotlight or lightsurce thingy the text is good.
is just perfect.
Keep it up! Practice more and you will be much better cuz i know you can do better ones.
Ow... and dont hurry things, you can realy mess the signature up
P.S. I think is time to change your signature, dont you think?
