Curious as to bipedal proportions, especially, as there seems to be good stylized, even with larger than life heads, eyes, yet they look "good". Is there a chart like there is for proper anatomy for drawing? It'd be great to see a comparison even though I realize there are many forms of stylized. I think that'd make a great article.

C4D Center is a great resource with free materials for Cinema 4D that you can easily download without going through cart processing. There are no limits here and new materials appear every week. Image-based and procedural materials are made with Substance Designer 6, Substance B2M, GreyscaleGorilla TopCoat.
It is really hard to find a better place for C4D users, so it’s definitely worth checking out.
