An Attempt at Composing a Halloween Boss Theme

A short soundtrack for the Spooky Tune Jam 2023, and my first ever soundtrack. Having mostly listened to slow (cafe) jazz and waltz, it was quite a challenge to compose anything outside of these genres. Although I personally don't believe it fits the theme of "Boss Fight at Halloween Night", feedback on how I can improve the soundtrack is greatly appreciated, especially on how I can make it more 
"Halloween-y."
