well to me the only thing thats missing is i wicked bass line to go with it....it also doesn't seem to have a main riff...only the background line that kicks in at 28 secs..
all i have to say is add a killer main riff synth a lil higher pitched and a heaver bass.
and mix the song up a lil bit, make it so that about 20 secs in you dont want to stop listening....and just when you think its gonna loop again for the next 20 bars...change it or add a new layer of synth bass etc. I'd like to see this song re-mastered. Make another one! Over all 6 for the effort!
