You were right it seems xD
From hearing this at the starting point and at the end i could see you two worked well together. The song was amazing before and it's still amazing now.
only problem i have with it is it still seems a little "flat" but other than that it is perfect. (sorry guys not going to lie there)
The Piano at the start sets the oriental feeling that the rest of the song seems to carry out and play with. The choir seems (in my mind) to bring out the fantasy side of things as well.
I dissagree with everyone here in saying only the piano screams oriental feeling. The strings do play their part too.
all in all though it is an amazing song, fitted to the use of any modernistic anime show or game and i will still recommend you guys to anyone who asks "Who should i get to help me with the music in my projects?".
I love your work Jason and Wf1. Hope you guys collab again ^.^
