Ah, use of PoiZone I see. That was my main synth usage until I found it easier to work with the more complex synth VST's.
The song is rather short (most ambient loops are under 10 seconds and I don't understand why), this could actually be evolved into a song if you add some drums, make it longer, and keep the variation flavorful.
The only problem is the overall harshness of the track, it definitely seems a bit too much.
