cool beat.
i think you were going for the simple approach but try for more complicated synths and see what happens?
also change the crash that comes in every 4 beats?
It really clashes with the smoothness of the song and sounds out of place.
also at the end (about 2mins) try changing that up and down synth with a app and see what it sounds like?
Thought i'ed give you what you wanted. somethings to improve on.
peace.
