It's true, the only thing that's different is the wig. However, this guy is so fantastic that he really deserves another page no matter how little the difference (seeing as CI only allows 12 images per costume page).
In his sprite form, Fou-Lu's hair looks more silvery, but in the manga and artwork it is supposed to be pure white. The new wig I got is a lot better, and better quality too than the first one anyway. The first wig (more true to the sprite of him) was shorter, and his hair is actually supposed to fall to pretty much the base of his spine.
I'm looking forward to doing him again with the group for London MCM Expo, October 2011, with theisaak89 (Ryu), Raye-chan (Deis), Sillabub (Ursula) and Emily Bastian as the Master, Una. We might have a Nina, but we don't know yet.
