The screaming type texture that comes in around 1:49 was unexpected, but welcome. Thanks for sharing.
This does have that marionette/puppetry feel. It also feels Halloween-y and could possibly be put in some animation. I feel like I can apply this song to some characters I've made who are actually puppet-like. xD
Anyways, this is fantastic.
Thank you for your long review!
Please contact me if you would like to use this in a project. We can discuss the details.
