A study I made after I got some feedback in this post.

The rules were easy, make as many different character faces as possible, the catch being they all had to be the same species. It felt a bit weird, since differentiating characters by their species was one of the reasons I started drawing furries in the first place.

The experiment was interesting, to say the least. I usually give all my characters the same head shape, but this time I had to vary them greatly. I'll keep that in mind from now on.
In the end I drew cat version of some G17 characters, just for fun. Ivo looks positively stupid with cat ears ^^
