The snare (I think it's a snare) feels kind of sharp at first. The dubstep sounds could be a bit smoother as well, and the fast-paced part starting at 1:13 sounds like everything's trying to be over everything else. Also, while most of the sounds individually sound fairly smooth, it definitely sounds like it needs some EQing to make them work together properly. I definitely prefer this to the original though, as it has variance, which the original completely lacked.
Honestly, the best way I've found to figure out how a synth works is to take lots of presets and toy with them until I figure out what does what. There could be several different ways to alter your sound in the way you want.
