Updating Modular Dungeon Set

I have been working on a modular dungeon set project last year and decided to update and revisit textures and props, to try and see how much I have improved so far.
-!Feedback or tips on textures or anything else is welcomed!-

The stage I ve left it then, looking at it now a lot have to be changed/updated.
(Note, I ve inserted a prop I ve made recently that I will also include in the scene.)

Current objective is to update the main textures such as walls/floor tiles/pillars/stairs and such, and figure out ways to diversify the environment, make it more interesting.

I have already started updating the wall asset with added geo and updated texture. I will use this to make variations if need be.
(At its current stage. I might add little things to it as I progress on to different props and such.)
I ve had a few iterations on this of course to make it better.
