Impressed
it has a very peaceful and relaxing feel to it, and yet it has a subtle hint of energy and action. This piece can be used in a HUGE amount of ways, in nearly any situation (if timed and placed right).
It got a little wierd with the flanger instrument, but it was still good there as well. I just think the transition to that flanger instrument should be slower and more fluent.
And then after that, the melody that kicks in, was also really enjoyable. I'm not sure if you used it, but a delay effect might be an interesting addition to the song.
