Maybe a lesson covering the anatomy of the face in detail with the names of the skull bones, origin and insertion of muscles and their names. I would also find the subject of hair a great lesson for such a beginner.

Maybe a lesson covering the anatomy of the face in detail (names of the skull bones, origin and insertion of muscles and their names). There are a lot of sources out there for that (I learned it from Goldfinger's and Peck's books, while studying NMA's 3D models.) But since there is no course on Proko covering that, it might be a nice addition for those who do most of their learning on this site.

That skull looks great. For sure, armatures and good things used to build them would be a valued topic for me. An additional aspect of insight might be with all the potential aspects of what to use as media, from oil based clay, water based clay, plaster, options for molds, digitizing and reproducing artwork, etc. Aluminum casting seems to be a thing now, and maybe much cheaper than bronze? 3D printing? What options are there in that realm? Marketplace? What do people want, what sells? How can we get our works put into spaces where they might be valued? Some general insights of any of that kind of thing would be valuable commentary from your perspective.

Oh where do I start!! Hair, that damn pesky thing. Sculpting different emotions. Eye depth in the face, I struggle with that one! subtle mouth expressions. Oh, just everything!
