Wow!
This is insane!!!! Have you been taking classes, or something? ;)
This is truly amazing. I agree with the guy below about this being in the top 50. But, the only thing that doesn't sound very convincing is the bass/tuba-like instrument you have around 0:13/0:14. Other than that...WHERE DID YOU GET THOSE SOUNDFONTS?!?!?!?
Keep it up!
