This looks like it could turn into a very cool temple map. I might suggest changing the fill of your walls to differentiate them from the stone floors. Even adding a shadow around them to suggest height might be enough. Also I'm not sure about the wood floors. Depending on the construction technology you could just use straight planks, rather than trying to fit them to the circle, or you could actually warp the texture. Depending on what software you're using this could be easy or hard. You can have a look here at my limited success curving plank floor textures. If you're interested in trying something like that I'd be happy to answer any questions you have about it.
