Hey ! I like the concept of this track
Also I think you can make it even better (it is just my opinion and one may think just the opposite and that is fine) :
- the fade-in seems a little be to long to me
- there should be no drums (or much quieter drums) before 0:47
- the transition with the modem sound doesn't do justice to the track so you may consider removing it
- the dubstep part isn't aggressive enough, the wobble should be louder and the drums should have a blowing kick
- the arpeggio of the ballad part is awesome but could be even more by modulating the low pass filter a little bit
- I'm not a fan of fading out the end of a song, maybe you could build a great finale by having a progressively faster switch between ballad and dubstep and something like a blast at the end
Don't misunderstand me, I like that track a lot and I wish I could have done it myself but I feel it stills has potential to expand !
By the way which synths did you use ?
