The Waltz structure in most of the tracks fit very weel with the tone of the game and the story. Is a nice mixture of Melancoly, Elegance and mistery. The instrumentation is varied and helps to define each character and location, like we see in Jester's theme, or the king's theme.
If i have to stand out one of your tacks, I would say Jester's theme was the one that I liked the most. I think it has an interesting duality, where the instruments are supposed to be happy and joyful, but the armony and the melody says the opposite, I like that a lot.
Good job!
