I'm gonna add a counterpoint to DSound on this one - he is right that a melody would help a lot - but I think this is really cool as a more textural based piece. My only comment is that I think it would benefit it to grow faster in it's arrangement and have a little more variation in the ostinato. This is a really interesting piece and it almost feels like being at a parade in front of a really awesome and unique marching band. Loved the textures overall. Great work!!
