I like it, so I leave teh comment!
Artful use of crescendo. I love what you did at ~4:50. Unique and captivating melody. Fantastic and subtle harmonics. One suggestion, personal taste, you could've finished stronger. By that I mean towards the very end have the instruments build up to a burst of symphonic harmony; bring out the bass, add a second underlying melody (soft yet active), things like that. That way the cutoff would be more stark and abrupt. That may not be your thing but I think it would be interesting to try out. Anyway, just a few suggestions. Honestly, I think this is amazing as it is.
