A zombie.
I just sketched him out, so he doesn’t have clean lines or anything. As far as I know, that shirt is an actual saying on another shirt, which I haven’t seen but have heard about.
Shading is relatively simple, compared to, say, my harpy picture.
Yes he has a green mohawk and is holding a skull. His lower jaw is also missing, as is an eye which was likely eaten by crows, and that is why is optical nerve is visible and spewing blood (which may or may not be possible, I’m not sure).
I’ve never drawn wounds on anything before, so bare with me.
