Just a bunch of stick figures mining in a large cave. However, there are a bunch of obstacles that block their way like clay bricks and metal walls that were placed there for some reason, which literally pissed the miners off and decided to break them all. There are even signs that prohibit anyone from placing bricks and walls since that gave them a hard time on mining.

This artwork will be a scene in the middle part of the movie that's about a miners who're mining for some minerals until they got stuck in the cave and decided to find a way on how to get out.
