I'm going to make a Rumia (Touhou 6) and bring her up as well.
Stuff I hope to do by the end of the year:
Prism - Original design: Done except for the bow
Akihito Kanbara (Idol) - Kyoukai no Kanata: Need to add details
Drag Cloud - Final Fantasy 7: Need dress, wig and braids
Bahamat - Fantasy 4: I need wig, and to make the wings
The Best Costume Ever - It's a surprise: All I need is the wig!
