i'd give it maybe like a 3/10... the colors were all... i don't know how to explain it... sort of close to being on the same side of the color wheel, lol. putting red beside brown kind of hurts the eyes a bit, and then the lighter brown just makes it worse. =*(
maybe make the background dark green or purple, and your name the opposite. like dark green background, dark green name, or vice versa. then you wouldn't need the little white line between the gyroid and the background (get rid of that line completely, lol). i think this could be a good signature with just different colors. =)
