Great song!
The intro really caught my attention :)
The evolution was perfect until 0:35, where the pad felt too loud and seemed to cover the other instruments. At 0:45 or so (also at 2:09), same thing with the pad that goes on and off like a wub; try making it more quiet so it doesn't ruin all the calm ambiance that you built just before ;)
Other than this, the overall arrangement/structure of the song was really cool. Nice song! :)
