Ahh, I remember when I first started :P
Time for some brutal honesty because that's how artists get better! This is what you call "D'n'B" there are no "wub's, wob's, yoi's" etc. You over use (to what sounds like) a glockenspiel sound effect. The bassline needs some working too. Because all you have is (exactly the title) drums and basses. The bass is a basic sine, so again no dubstep.
Try spicing it up a little more next time.
