Had a quick listen, but too tired for a lot off comments..so just some first impressions
You asked about progressions:
Thing that jumps out for me is that almost the entire song feels like the second half of a song. You know like it builds up from something, but that something is missing. The chords they reach up but from where? Maybe just start with the beat and that bass sound. Then some basic chords and other sounds. And after that the building up parts (which now are the start of the song).
Another thing is prog trance for me is Sasha/Digweed/Global Underground series. Don't know if you are going for this or not but if you are it could be a bit more subtle. Those snares really aren't subtle. If you are not going for that sound, then just ignore this comment
