Took longer than I thought, as there was quite a bit of info to get through, but I finally finished the breakdown for this project. You can find the full version for free on my Gumroad page here: https://gum.co/jKeNY.
I've posted the most important parts here if you are comfortable enough with the process, but because it's quite long, the full version is on Gumroad and also includes the files you need to create a similar project.
Hope it helps you in your future projects and if you are having any issues just let me know!
