I reached the end of the course and I really learned a lot! I tried to understand the math behind all the steps we have taken, so at times it had been really rough to fully understand what is happening and why, but Im glad I kept going! Im now much more confident in Blender Materials and feel well suited to create my own materials, but also I have more tools to work with, for example some things I have done in sculpting previously might be better done with procedural materials. Thank you so much Stephen! Really enjoyed following along! 
Im now off to work on the Geometry Nodes course!
