Cliff side fire pit.

Nice, you used a vector displacement and simple shape or painted shader? Needs a neanderthal.
It is a Cave object I got of the World Wide Web.
I deleted most of it except the back wall.
Then applied a PBR.
The smoke and hand prints is a .png i made in GIMP and applied to the object.
Paleolithic humans would have needed deeper caves lest a dire wolf should wander by and get curious... :o But I like the concept - nice work!
