I worked on the wall textures a bit, and I think this improves it. I added in cracks and such to make it less monolithic and more varied in texture, as well as played around with the highlights and shadows to create some variations in color on the concrete. Hopefully this is an improvement.

I like my stair down into the pit, but my stair up... that's not interacting with the rubble quite right, going to have to half-destroy it or something to make it work. Additionally, I think I'm done adding rubble until I have the upper levels visualized and the amount of ruin going on up there.

I'm also looking for ideas on what sort of castle / dungeon props would remain after a thousand years of wild animals, and half-sentient monsters wandering around the place. (That's yet another challenge for my poor hand-drawing skills!) Also, my floors are too clean, going to have to grunge and crack them them up once I get props inside.
