I loved it!
You've made some very bold sound choices. Especially the one we hear at 20" that picks up the melody at 40". It sounds like you put in a lot of detune.
The whole soft part with the glissando is very pretty, and the build-up to the more energetic part is really well done.
On a technical note, your cymbal crash is below the quality of the rest (you can hear it clearly at 1'17"). What's more, while the other instruments are well mixed in stereo, this one is in mono.
Otherwise, it's great.
