Wow! Are you sure you didn't pluck this soundtrack directly from a film? ;)
Really great work my friend! The whole thing flows so well from one track to the next, and the orchestration is just so authentic. The dynamics across the board tell a story by themselves as well. The quiet parts are effective and let the louder parts speak more definitively. Everyone could learn a lot from this!
Outside of film and the game you made it for, I got a lot of Final Fantasy 12 vibes from this as well, especially from Limbo!
