Thanks for all the comments guys!
Very interesting story and a cool scene to go with it. The walls look a bit flat in some places, but your fig posing is terrific
Yeah, I tried experimenting with adding various bits and bobs to the walls, but it ended up looking too cluttered. I couldn't find the right compromise between decorated and flat, so it ended up staying plain. The next scene I'm planning is out of the cave, so expect it to be much more organic.
Thank you for the comment!
