Wowee what am ambitious track at 7 and a half minutes long. For such a long track you've done well to maintain interest, but it starts to feel a bit too long by the 5 minute mark for me. The reason is because there isn't any melodic development - you filter things out and bring them back and add an extra pad but there are no new melodies to enjoy. It's a pretty good track with nice sound design and good production but the musical fundamentals need work.
