Just found these on a non-english version of the Grimm wiki. (For the life of me, I can't recognize what language its written in. Sorry. One of those days.) It has what I assume are concept art renderings of the Wesen spiecies. This show got me into the furry community and it is interesting seing the designs rendered as paintings. The Steinadler, my favorite (Farley Kolt FTW) is awesome and the Seltenvogel is beautiful, and from me with no sexual interest in furry creatures. Shame they changed her design for the actual show.
Wesen - Wiki Grimm
Where would these fall on TV Tropes' sliding scale of anthropomorphism, I wonder?
