Did... Did you really make this without hearing anything until you were done o.O? That is definitely a Beethoven challenge true to the core!
And to add to that, this sounds incredible! The chord picks are nice, and the harmonies and melodies are very atmospheric. The flute might have a little bit too reverb for my taste, but in the end, it sounds pretty good regardless.
Heh, I didn't expect that electronic part there at the half way point (I hope nobody reads this and has it spoiled; in that case... Sorryyyy), but it too sounds incredibly awesome. And the combination of both at the end is just splendid.
Brilliant job with this one! Favved :3
