Not sure how long you have been making dubstep but your not to bad at it. Regardless of you doing this for a while or for a short time, you are on the right track, keep up the good work. All I can really say is try to add more drops try to avoid making the song the same thing over and over, maybe add a new drop near the end to end the song with more of a bang.
Yeah I figured; I'm just a lazy ass. lol
