Not bad!
I think the drums could have been improved a bit in some parts, and the kicks (which pretty much define techno) could have been a little stronger/interesting. You also had almost too much variation; you didn't stick with a melody or beat for more than four measures or so.
Having said all that, you had some good melodies, some good choices of instruments (you could have used some slightly more interesting synths, but here they do the job well enough). Also, the slowing down at the end of the song took too long; honestly, I think it could have ended at 1:58. Keep it up!
Overall, 7/10, 4/5.
