Listened to the whole thing, had a few initial feelings on arrangement. This is just what I'm hearing, and if you implement my suggestions, they may very well sound sucky, but here goes anyway...
-When the drums come in at :48 seconds, put a gong in for a more powerful drum intro.
-From 1:03 to 1:10, have the drum beat cut out entirely, then at 1:06, cut out the string track, so it's just the bongos, then add some chimes and have everything come back in at 1:10.
-At 2:34, have the drums cut out for a count of three, then come back in as normal, (example, the snare drum on 2 and 4, mute the track so the beat comes back in on snare hit 4) maybe mute the track for that duration so the beat stays in sync.
-At 4:10 to 4:31, put a lot of reverb or delay on the floor tom shots, also when the drums come back in at 4:31, try adding some chimes.
-In the overall drum track, I hear some sporadic syncopated clavi shots, maybe some tambourine, something to break up the loop somewhat. Don't know exactly where, maybe just try experimenting with different forms of percussion and see what sounds cool.
My two cents. Maybe you can squeeze a quarter out of it. If so, could you buy me a gumball?
