im gonna slap my vote for teh kuwa.
His sig follows my personall rules for a sig, an image, text, bg and effects, ryoko slipped past a stock image and has caused a serious blow the the overall visuals of the sig to me.
Kuwa's sig once again has lubblah effects placed all over sig, and personally i think the image suits the sig, although a samurai style pic wouldnt of hurt.
Ryoko's sig is good because it is finally a sig with no anime lass in it. problem is, there is no pic anywhere, leaving all the space unoccupied and wallpaperish. If you slapped on a graphic that suited the scheme, it would look so much better.
Thus teh kuwa claims my vote for today ;O
