I'm really happy to see Idolm@ster really take off! I'm helping coordinating a New England based Idols group. We're probably looking at doing things for Anime Boston 2014 since most of us in the group are working on eternal sailor senshi.
I recently did Azusa's marching band variation at Katsucon and PAX East:
For Otakon, I'll be doing Ryuuguu Komachi
I think there's an AX 2013 Idols group in the works, but I'm also trying to get a rough time school group. For the life of me, no matter how many times I google-fu, I can't find for the group shot art for rough time school. Any help? Thanks!
