When I saw this had hit the frontpage I felt a little bad for skimming past it in my news feed. Wow!
This has a retro Final Fantasy feel to it - maybe VI or VII, with the beat reminding me a lot of Glass Fish Rhythm. Your background ambiance adds a really organic element that balances the chiptune incredibly well. It sounds a little like it runs out of steam maybe 2/3 of the way through but the mood is really mature and shows you're upping your game at a pretty steady pace.
