Have a listen and let me know what you think. Heres the youtube link:-
everything is really tidy, but perhaps a little more work on the wavering volume stutters on the pads? the idea itself is fine and fairly standard for a lot of tunes. But i dunno.... i'm too tired to get the right terms in my head to explain... i get the feeling the volume quick-up/down-fades should give a relaxing wavering rather than jerky stutters. so maybe imagine them as square waves with rounded corners rather than almost purely square up/down fades?
keep up the nice work though. worth making a finished piece for sure.
