I really like this idea
I haven't heard you use this key very often, and it fits the theme and tempo really well. The only thing about this song that sounds completely off is the tone of the bells; it mixes with the song really badly. I like the idea of the bells resonating, but their tone stands out a little too much when the rest of the instruments are playing. Other than that, this song is fantastic. I really want to hear it when it's completely done!
