Do you want to know why you got a zero?
because every part of this song is a pre-made loop. The only originality displayed by this song is the organization of the loops. It would have been better if you had chopped the loops for the individiual string instruments and used those instruments and the piano roll to make your own song. You didn't even change the tuning, slow it down, nothing! This is effectively stealing someone else's work!
Go home, rethink your actions, and come back again with something truly original.
