As a learning lesson and test I revisited one of my first materials (from 2017) and did a complete rework. I also wrote a blogpost about the process and the comparison, where I wrote about the problems the old material had, what I improved, what I learned, what my focus was and how I constructed certain parts of the material. So check it out if you are interested.
The last images are a comparison of the old and the new one, it was a great learning experience and I am quite happy with the result.
I hope you like it and feel free to c&c :)
