Hmmm! Couldn’t get your remix to play. The link took me to the Soundcloud page but nothing happens.
Anyway, I heard the original mix and it sounds great! Very professional, great mix, nice instrumentation, good vocal melody with tricky effects and a sound with a hook.
I agree with comments on the repetition but to tell the truth, it may be hard to restructure the song without taking away it’s signature so my suggestion would be to simply make it shorter. I found myself looking at the elapsed time at around 2 1/2 minutes so if you started a slow fade at that point and cut at about 3 minutes, it would aleviate it of most of the repetition factor. This of course is just another idea considering you were having a hard time with chord deviations. 
Edit: I also just had an idea for a part that would break it up a bit without infringing on the song idea if you’re interested.
Good luck!
