Ahhhhh, Ambient
You captured that essense I think. Nice simplisicty and melodic interplay on your instrumentation. I think it's fine without ever developing a hardcore beat since very few Ambient tracks are meant to hit hard anywhere along the way. Love the synth dropo-in at 2:00, but ya shoulda kept another background instrument before the piano came in, like the tinkling bells synth. This coulda been a powerful wave of synthesizers coming at the listener from all directions, with that saw in the mid channel, piano from the right, and a nice wavering bell phasing from left to right with a support synth on the left channel. As powerful a sound as the saw is it begs for some crazy phasing effect work to make this pulsate. But all-in-all a superbly put together ambient piece.
Keep it up.
Peace
