Very pretty~ I love the color themes and the shadowing; it ads depth to a sig with no background~ Everything's organized in the signature as well, but...the back picture in the avatar kinda makes it look a bit too large...otherwise, maybe a boarder to your sig would look cool too.
8/10
EDIT Faster poster! >: I'll keep Jyukai's anyway.
It's animated *-* I'm not too muc of a fan of sprites in a signature, but it matches your theme colors, especially on Quilava's Glaciation. Friend code might belong somewhere else, but besides that, it's very simple and pretty~ 7.5/10
