Andy, I think this piece needs more energy. The instruments sounds synthetic for my ear.. You should try to make it with other libraries and try to use more dynamics. And the critism is: I don't hear any general melody in this piece? ? ? Where is it? I hear just harmony. Maybe you should try to compose it? The idea is very interesting, but you should work more on it. Waiting when you'll finish it! :) If you don't like my critism, sorry for that - it just my opinion! Keep it up!
