If I thought that I could pull it off, I would totally do Rinoa's hairstyle. I love how it's dark, but there's some subtle highlights in the front. It frames around her face really nicely too. I can't do it, because I don't have the right bone structure for all the layering that's going on.
I would also do Ashe's hairstyle, but I don't think I would want it that short. It looks nice though.
