First thoughts: For some reason I keep being reminded of the Portal 2 OST - especially some of the filtered basslines and builds I keep expecting Wheatley's leitmotif to come in. It could even be interpreted as a new genre-take, even if it wasn't intended that way.
Don't worry, I loved the Portal 2 OST :P
I very much liked the composition of the piece - the less energetic parts transitioned well into the build-ups, and all in all it was a great listen. The ending seemed a bit cut short to me, though.
Your bassline synths were good, but the others did get a little repetitive, both in melodic and instrumental terms. But it definitely is a sound for DnB I've not encountered before.
I guess in summary, you've done a great job! Looking forward to hearing more from you!
