Wow, that sounds really cool! I wonder what it'd sound like performed? At the part where the tempo increases to 172 to the half note, I think that it should be written with sixteenth notes rather than eighth notes, which would make the tempo 172 to the quarter note. This makes is much easier to read and comprehend when learning the piece, because when I first saw the eighth notes, my initial thought was "it's not as fast as it looks", but it's way faster than it looks. You also change the key signature quite often, which is really cool and I like that, but you don't put any actual key changes in the music. That would be helpful to have, to let the player know the key is changing rather than having them look at accidentals the entire time. Overall, the piece sounds awesome and really fun to play!
