Rhubarb

Hey all, this is actually my first post, I'm sure there'll be lots more to come since going in to a job has made me increasingly desperate to search for any opportunity to spend my time on music and with musicians. This is a short science fiction movie trailer piece I wrote when I was in school. I had a lot of ideas at the time but far less definition than I do now, so if you could give any explanations as to what makes certain parts of the piece work, particularly where dissonance is concerned, and how to make other parts better, I'd be really grateful. Thanks! (oh and headphone warning, I'm not sure whether I mixed this thing back when I exported it so the very start might make you jump, other than that it should be fine)
