I modified this from a open source grin photo that I found a long time ago on FA, i believe it was a black and white wolf or fox , the drawing was made by  adjot and can be found here https://www.furaffinity.net/view/5234137/

This is why you do not piss off the doc....if he looks at you like that you better be hoping you can run otherwise you are going to suffer...

This one took a while to do because Psyche isn't exactly anthro so spent a lot of time making the grin base work. It was pretty much totally re drawn , even the eyes were re done a bit but i still used the original photo as a guideline
