As for the BGM, we found a profession studio to work for us. At first, he refuse us for his tight schedule, but after see our animatic, he said that was very attractive, thus agree to cooperate with us. Kinda proud!
It's called Production Yuan http://www.weibo.com/productionyuan?refer_flag=1001030102_&is_all=1
I first heard of him at last year CUC's animation graduate screening. He composed for a short student animation I liked.
I'm so happy that he accept our work!!! Big progress!!!!
