The pad gets a little bit too loud, i think that it may be better in the background with a little more reverb. I love the bell sound.
Cool bells! Has a very spacey sound thing going on. The pad swelling back and forth is pretty much the only dynamic movement going on, though. The bell seems to be on an LFO, but it's being overshadowed pretty hard by the pad. I think those are the only two instruments playing, too, which is pretty minimalistic, even for an ambient piece. Have you tried other subtle effects like panning and stereo phasing?
