I feel bad for doing something as spammy as pretty much registering to this forum to make one post, but here it goes.
Since 2011 I'm reading the comic, and back then I started with some piano pieces related to it... but I never got so far as to record them, until this year. And now I haven't just finished what I begun in 2011 but am continiously adding to it since the summer. It's a lot of fun and I want to share that here to other fans of the comic:
As I said, I'm still working on it, adding pieces here and there. Originally I wanted to do leitmotifs, but it got scrambled up, and what was supposed to be Kat's theme is now Jeanne's... so no leitmotifs. But I intend it so that every piece is connected to at least one other peace either by sharing part of a melody or some other structural stuff. Gunnerkrigg Court has always been strong on hidden symbolism, and that sounds fun to try to emulate musically.
