A few years ago, I did bone anatomy of a Shifter, and wanted to continue on that same path, giving a very scientific look to my fictional species. And with the aid of some recent art refs, I figured out some new things to tweak about the basic Shifter design, hence why I redesigned my persona above.

I would honestly love to redo my Shifter anatomy notes and such, since I just love having some sort of answer as to why and how they do what they do.
