As said before your song is different. I like it. :D Scouted
I see much effort given into your song. Can't say much to your mastering because imo you mastered it very good.
I would turn down the higher frequencys a little but thats no big deal.
I'm afraid to call it techno. I would say its Chill-Dub.

First of all: Great work here!
I like the song slowly building. Great use of FX in the Intro and the white noise sounding synth. I would turn down the Volume. I like the chords starting at ~3 min but in the tension building part after the rhythms feels choppy. Good reuse of the intro after that part I enjoyed your song till the end.
Good work in mixing tho i would lower the cutoff of the kick but thats just me.
