Very nice sound overall, I'm not sure if, on the intro, The drums should be un-passed with the rise or not, but it would be something worth experimenting. I believe some reverb could be used on the abruptness of :58, I think completely silence should only be from extreme to extreme, not extreme to rise, (Like at 1:44).
It's a little loud" as I get a little distortion on the main synth, It sounds like your going for a jumpy wub towards the end of the song but it's "stuck" in mids.
Please contact me if you would like to use this in a project. We can discuss the details.
