Really great melodies throughout the entire song.

Great Job

I liked it within the first 10 seconds.
You nailed that ATB bubbly-sound at the beginning.

Constructive Criticism
Perhaps add some more emphasis to a beat in the first 1:30 minutes. The arp in the background coming in created anticipation and I expected some sort of climax for a while, but it never came. Add in some drums that build up to 2:03 and perhaps a crash or something would smooth it out. This is all my opinion of course.
