Dear Nick, with Your permission I'm adding this dungeon scene sequence into my Nick Harris file that I keep among artists and illustrators who are examples of style and visual tutorial to me.
I see that You worked on a finely tuned contrast between green/yellow and pink/ purple in here and that You eventually decided to have the standing prisoner too sleeping, although in a clearly less comfortable way.
The third and mostly disappear prisoner, who just left part of his arms bones and organic liquids leaking, that fed the mould on the pillar, prematurely passed away while in the Lamarckian adaption process that was apparently leading him too to have elongated arms to better cope with the environment.
Big claps!!
