It isn't bad, the melodies are nice, but it's lacking variety. For a 6 minute song listening to the same melodies over and over can get boring. The extent of your variety is letting different instruments fall off and bring in a more quiet tone and then bring it all back until you're about 4:20 minutes in and then its a completely different song and feels like it has a bit of an identity crisis because nothing lead up to it.

Also, that instrument at the beginning that starts at 0:25 has too much reverb, sustain, and/or decay. The notes end up fighting with each other and you end up hearing a nasty 3rd dissonant tone that doesn't destroy the melody, but kind of muddies what would otherwise be beautiful.
