So this is an old work of mine. I personally like to draw all kinds of hair styles for the bunny girls I do, and I thought. Well, some of them have the ears exposed! soooo.. what happens to the human ears??

Some cross-anatomy between cats, bunnies, and other similar animals along with the human skull; and we got this. Some form of wavy protrusion that exists in the place of the ear.

I'll probably do another version of it soon as I have since studied more anatomy shit. We'll see
