Rich intro, really warm.  Like the synths, a very abstract feel to them.  Nice steppy beat.  I love the way the beat really picks up.  But I would like to see even a really simple bassline that had sustained notes to come in with the new heavier beat to give a really strong standing ground.  Love the beat change ups once almost all the synths drop out.  Nice use of delays and reverbs all throughout the song.  Nice depth, and gives a feeling of room to breathe.  The way the track is structured is really nice.  Just like the synths, its really streamline all around.
All it needs is a new bassline to give a backbone.  With the way the song is, really dreamy, and good depth to the atmosphere, with a deep bassline it would add to the encompassing feeling.
