I definitely like where you're going with this, it's definitely got some great potential. I actually didn't mind the organ, it gave it a sort of "in my time of darkness" feel, which was how I always associated this point in Beatrix's/Steiner's story emotionally. Maybe back down the volume of the organ a little bit, I guess, to avoid it being too sinister-y like Archangel commented.
I do agree with Rozovian, though - there definitely seems to be a bit of a fight between the bells and the piano.
You might also consider bringing the strings out more, separating them better from the piano.
I love what you've done with it so far. I'll be watching for updates to see where you take it!
