Very nice. If at all possible try to experiment with a Soft and/or Dark Append of Miku's voice. hopefully the end result of this project shows this song to be Much longer ( I likes me the longer stuffs that go on between 5 to 15 mins)but if not this is still great. if your looking for some inspiration I would highly suggest looking up artists such as Clean Tears and Hiroyuki ODA as they are very good at making as well as remixing popular and well known tracks in the volcaloid community. Keep this up and I will be following your progress!
