I like the beginning, but not so much the rets of it. I like the atmosphere you were attempting though.

Great idea and great song, just a bit too muddy.

1:18 the melody is great but the bass lead behind it ruins the buildup. You could have used an offbeat rubber bass here after 16 bars of the melody to really create an awesome buildup and atmosphere if you combined it with a pad.

Effects here, namely the sweep at around 3:12 is amazing. Really seals the end of the piece and is better than your average boring reverse crash. Good addition!

Maybe get rid of more instruments towards the end instead, maybe you could have squeezed it out to over 4 more minutes doing this.
