I Love the signature your using now. It's great. Brown is rarely used in signatures, nice that you've used it.
The Alexandria one is ok. Aqua looks a tad strange for sigs. It looks sortve....chlorine like.
EDIT - Stormbreaker. I've never heard of this cokeclassic guy. But there are definatley other people who are better than him. Genji (always keen to make a signature). He has the most unique style on the forum. And im nott sure if Voodoochild does requests. But he pawns.
