Fix your volume.
the backwards thing is really odd, and since you use it so much at the start it makes it seem like you have no real idea of where your going. and then you get to 1:47.
such a DRASTIC change in volume is really REALLY weird. its like cool, cool, BAM, my ears just died. its sounds cool from then on, but the volume is to high, and its clipping the base, and then when you change beats COMPLETELY at about 2:30 its really odd again.
and then AGAIN at the end, there is some REALLY horrible clipping issues. like. really bad.
basically, work on your levels. lots.
sounds cool, but the changes in volume and stuff hurt it.
