Really exciting piece, was wonderful to listen to. The harmony especially is super fun, tastefully dissonant and suitably wonderous for this magical castle. I would critique that the track only occasionally dips into the more ethereal, reflective ideas I would normally associate with crystal castles in video games, like the string interjections near 1:25. Ultimately, that part of this comp is pretty much up to interpretation so I'm not marking it down particularly harshly for that. Nice work
