HOLY CRAP THIS IS SO HEAVY UGHHH I'M STRAINING UNDER THE WEIGHT...
Heh, I don't usually listen to heavy techno, so you'll have to forgive me... I like the chord progression you were using - it's nice! my main criticism is that when the really heavy bass comes everything gets really really muddy, especially on the low end. Do you have some crazy amount of reverb on your kick or something?
I'd also maybe like some sort of detuned saw doing some cool melody or something.
By the way, along with what EternalEndeavor said, this song is quite repetitive. I personally prefer shorter songs that are less repetitive - as a listener, I can always just put them on loop if I like them, plus as a songwriter you get to optimize your melodies and things over less time, so you can make them better!
Anyway, keep at it! (And don't take the "low" review personally - I try to review so that 5 is average.)
