I agree with Genius Lynx, the font is a very good choice as you can read it throughout. I really love cloudy day, I don't think it could be improved very much since it's really genuinely good.

If you want any other skin ideas, I'd suggestion a Frocobo skin!

EDIT: Oh actually, my biggest suggestion is just round the edges around the big grey forum index and forums list box, like Monda did in her screen shot. idk if you can or not, but it REALLY make a difference to me even though it's a minor detail.
