A good start to making this better would be to have the main snare playing a steady, traditional snare pattern (on the third beat), also, do more with the drop instead of just alternating between two pitches. I think it needs some type of harmony or texture, cuz it kinda sounds rough. And definitely spend more time mixing this.
this sucks. sorry to burst your bubble, but its not dubstep or big room or chords- its trap, which I suck at. good luck to everyone else in the remix comp! ive probably done real bad.
