It's atonal; you could do much better.
The synth IS harsh, and annoying, no matter what genre you put it in. The parts in between are nice, but that crazy smashing synth noise is simply amelodic. Not really satisfying as music as a whole. I understand you spent a long time working on it, and it does sound well polished, but it's best part lasts less than a minute before being intruded by the monster synth. If I could close by saying that I love jazz, but I hate the random noise that is avant-garde jazz. So it goes with this, I love techno and electronic music, but this is atonal and not enjoyable to listen to.
