Melody
i would have to agree with chalkley3...this piece lacks debt i believe becuase there really is no melody its just a repetitive loop of a short beat so as a listener it doesn't take me anywhere ( i just got to the door but didn't get to kick some booty). i would suggest to expand on the small melody that you have and the rest should fall into place. your percussion is fine but again it can't grow itself becuse there is no melody to change with.
