Great work here. You really know how to make a song interesting in terms of instrumentation.
The piece managed to keep me interested throughout the whole 2:17 of it. I was expecting that the beat would go on after the little pattern you've introduced. What was your reason for just playing that once? It does make it more interesting..

Did you use any compression on the whole song btw? It sounds a bit too compressed at some points, when the recorder-like instrument kicks in. I think the song would sound better without the compression.
