Nice pen tooling on that first sig RD! Though I think you could maybe fill some of the negative space in the bg a bit, or maybe add some text or something.
lol@"hawt" sig. I was wondering who made that one in the battle ;x I love the very soft look it has, but wish the text weren't quite so washed out.
Love, love, love your vertical sig. It's unique and the colors are awesome. Overall all your sigs are really great. You don't ever settle on one style or rely on one technique too much which I really like.
