The main two I have my heart set on are Zexion (KH CoM) and Seras Victoria (Hellsing).
Thinking about Canada from Hetalia. I'll probably do that if I have time after my others. Idk.
I'm also doing Zoey (Left 4 Dead). I know she's not very Japanese or anime-ish at all, but I just like her a lot. XD
I think I'm going to give my American McGee's Alice and female Luigi another go, but I'm not 100% sure.
