Disclaimer: this is not a tutorial!
I have recorded the entire process behind the creation of this Halloween loop I up together in a couple of hours. I didn't really plan anything, that means it's basically one hour and a half of trial and error, wrong tests, aha moment and After Effects bugs.
Hope this will provide some useful insights anyway.
