From 2016. I believe this just has a loose blue line sketch, and the rest is Sharpie.
One of the things that’s fun about drawing the Marvel Comics Symbiote characters is that you can kinda do whatever with them, because they’re wearing alien slime suits. So if you want to, say, draw Carnage a little more swirly and goopy, it’s totally fine.
That body is probably a little too beefy for Cletus Kasady, though.
