Not bad at all.
I only have one complaint, if you can even call it that, and then I'll get on to the rest of the review. I do think it was quite repetitive. It almost sounds like most of the song is just the same thing looped over and over. That's perhaps not a bad thing though. It could just add to how calm and relaxing this piece is.
To me it sounds like great music for an introduction or credits to a flash game or movie. I can see the slower parts primarily being used for a slow rolling credits. I get an overall relaxing fill from the piece of music. Maybe you could use some vocals? Not like someone really singing, but I can see a count down being used in here. Something that's just a voice saying something every now and then in the song.
Keep up the good work.
