This is a really nice, warm and good sounding OST. I especially like the opening music, really sets a grand mood for the game, and the beutiful ending piece is really soothing for the mind and soul.
The Perpetual Pendulum of the Moonlit Clocktower is also a beatiful composition that would work in any movie setting, and possibly my favourite of the bunch.
The more "whimsical" music made me think of a kids cartoon TV-sereis; not sure if that's the intention but that's the images that I got from them.
All in a ll a very elaborate OST and some really great tracks!
