Considering most of the stuff I listen to is Dub and Hardstyle, this is a nice relaxing piece. The beginning is genius, and when the main rift came in I was in love. Keep it up, I can't wait to hear the next one.
The nature sounds at the beginning was a nice touch. I just find the repeated bird tweeting annoying. o.o
The song itself is a bit simple, in terms of instruments. I'm just hearing the same saw pluck and kick drums playing again from the beginning to the end. You should use varied instruments, the song got kind of boring after a while. Maybe some pads in the background will help, or playing the melody with another synth.
Overall, it is decent. The melodies, although simple, do help give this song some action, and the kick is sufficiently 'punchy' enough. (Maybe too punchy o.o)
