I didn't have time to create drawings of my own for these tests, so I grabbed some free templates instead. That being said, apart from the ears being too small, they're actually pretty good matches. This one was drawn by Vosska on DA.

Did this one after deciding that Pickle having natural coloured teeth and gums made far too much sense. I'd also been toying with the idea of giving the upcoming fursuit head a glowing mouth (again, for no reason other than 'because I can'). Green looks best, I think.
