AH! You'll be doing a Sister Kate at Ikkicon!
I'm bringing my artbook Tres if I can finish it up in time.
Everything has been crossplay for me so far, but the current list is:
For Phoenix Comic Con, Dark Walter
Military dog Edward Elric (in uniform)
Kyo from Fruits Basket
Tres Inquis Trinity Blood
For Anime Expo
Mika from Angel Sanctuary
Level II Alucard
Crossplay on, everyone!
