Old Ones up in this bitch.
This doodle is based on a piece done by, well, I don't know. If somebody who reads this (nobody) knows whose piece it is, comment with a name, so I can credit the artist. But yeah, obviously it's a doodle of Shub-Niggurath. One of the Great Old Ones, she gives birth to tree-like creatures called dark young. I like to imagine the blood is from her giving birth to the hoof, head, and whatever is beneath/behind her. Just a doodle of an Old One, probably the only one I can do besides Azathoth, given their nebulous form.
