You can consider this one either finished or not finished, depending on your perspective.
Jokes aside, despite not completely finishing one (basically because I was tired of drawing so many skulls and just let it be), I'm still satisfied with the results. I can still think of ways to improve it, like any other illustration, but I think I achieved my goal with the drawing and it's concept.
I might make a digital version of this one in the future, but I have other projects I'm more engaged to at the moment.
