Was browsing to see what Feng Zhu had to offer and I found these.
I've see sketches of the drill digger. I can start modelling that out asap but in case I can't, there needs to be a backup plan. For now Plan A though.
It's like he painted what I had in mind but way better than what I could do. If we take those shapes/visual language and such and apply our own design, I think we can knock this out of the park. We still have magma and limestone stala(gm)(ct)ites and rocks so break a bunch of that into scenes like these and we could have something awesome.
