Subdrops....
The synth opening sounds really nice! i just think its a bit too long of an intro...
Im going to be specific...haha
1. When the drums come in at 0:13, instead of having a kick pattern, i think you should go straight to a standard dubstep kick and snare.
2. Like i said earlier, have the drop earlier and harder. Try putting in a reverse crash or white noise (watch youtube tutorials if you dont know how) to make your drop harder.
3. I dont know too much about dubstep drops, but i dont think the first dubstep part really matched with the high synth.
4. I also think you added too many subdrops in it....dubstep can sound a bit messy if you go overboard with it.
5. The wobbles sounds really nice with the High Synth, so keep the wobble, and change the other parts of the dubstep a bit!
Keep up the good work!
