Wow, great!
I really liked Robert Miles' Dreamland album and still return to it in times of emotional difficulty. I think you did a great job with the grit you introduced to such an innocent theme while maintaining the basic textures... Should be three times as long and develop more. at 2:07 the song should continue to build into a full fledged section with chord progression interacting with the beat. For an example of what I mean, check out Dave Darrell's remix of Miles' "Children".
