The kitchen part, above the character, is unstable at best. Try to use it and it will fall onto the ground the moment you push your hand on it. I won't comment on the lack of a water source (no faucet, either it's missing or they use buckets of water).
The kitchen was a bit of a dilemma for me. I could shrink it and have it fit on the rock more, or keep it as-is. I thought it looked less odd like this. It's not meant to be "precariously perched" but rather part of it. I can try to work on that? But yes, there's no running water in this community, and that's addressed as a major point in the plot. They use buckets by going to aquifers. I'd get rid of the hole, but then there'd be nowhere for the water to drain!I wouldn't put a sink in there at all. It has a plug hole, but it's sitting on solid rock, so where does the water go?
This crossed my mind while mapping (notice the big pillar is the color of the walls) but in the end I decided to go with different colors. There are lots of different rocks under the earth. Some clay, some sand, some crystal. Using the same color for all the rocks made the room plain. I liked being able to make the corners and furniture stand out from the walls more.I think you also need to edit your rocks a bit more. They are much lighter and brighter than the rock which makes up the wall, so that they do not look like they come from the same general location. Why import rocks from somewhere else when there is plenty locally? They need to be much nearer the color of the walls.
Because it's a cave community and they sleep on rocks/dirt, yes some rocks/dirt of different colors taken from elsewhere, and yes different shapes and sizes.Beds on rock piles? If the people there are able to cut rock (since they did so for the bookcase and such) why would they sleep on round rocks?
How did they manage to get a rug *under* the rock piles?
You *could* do without a hole, it's fantasy and players probably won't care. But common sense dictates that there should be one. Hence, when something feels unnatural or illogical, we pick it even in a fantasy setting.I'd get rid of the hole, but then there'd be nowhere for the water to drain!
