the sig looks great, but i want to give you one advice:
when you save your graphics in order to use them online, save them as jpeg (if you use photoshop try save as for the web) and the quality to be only of 95%. If you save it as png, it uses a lot of space and somethimes it loads hard
one of these days i'll post a photoshop tutorial for making sigs or anyother graphics. i'm slumped with work right now, i barely have time to visit the forums and make the update (news & recaps)
there you go, have fun. if you're enjoying it, i might re-open the graphic forum for you to post all your work there (wallpapers, signatures, avatars, etc)
