Very nice soundtrack, experienced with the dynamic visuals of the video (very well done by the way) and your explanations of the story it deepens the engagement and appreciation of your work !
The instrumentation was pretty well thought out and chosen for what you had in mind (the tracks sonically reminded me a bit of tracks from Monkey Island so it isn't that far off). Concerning the instruments association to the characters in the dedicated tracks, maybe I would have liked The Bells Of Battle and As A Bell Tolls to have their main instrument be more central (the vocals and bells do appear but maybe not as much as expected for being themes of characters, that's just nitpicking though).
I do feel that the tracks that shine the most (and also my favourites) were A World Of Hold & The Citadel Beckons, where the instruments representing the characters can each take the spotlight when needed to serve the storyline, I think those were the most well done !
Overall congrats for your very impressive work, thanks for sharing !
