Tbh i liked this. It has potential, but sadly there are a few things that bring it down.
1. the drums are fairly flat and bland, you need to distort, eq and compress the hell outta them. Look up tuts for them, their are plenty.
2. It was very repetitive, i would shorten it to around 3 minutes, that way it doesn't get boring.
3. you need more sounds, and more sub synths. And your bass was a bit over powering. Kinda sounded muddy.
On the flip side, the very first bass synth was pretty bad ass, and i enjoyed it.
