Nice Work!
I enjoyed the task you were trying to achieve with this song. You set the mood well keeping enough environment in the song to keep the listener interested.
I do suggest that your main synth should be worked on. it seems to slice through the song a little to sharp against the other instruments. the synth doesn't have enough strentgh or elaboration to poll off the position you gave it.
melody was great as well as the bass and percussion!
if you want to work togethor sometime let me know!
