In this update, I wasn't happy about the way I did the wood slats in my last one, but rather than edit the existing ones, I created some new ones. They all use the same basic wood grain as I made for the "elegant" style wood surfaces, the difference is one set has larger slats, and the new set has a more realistic slat size which should translate to somewhere around 6 inches thick by 8 feet long (or thereabouts).
I put these new ones in their own folder called "thin wood slats".

I've also added 3 new grass textures. Same texture, really, I just edited the coloring a bit to get you a light, medium, and dark version.

The original wood floors were a bit "elegant" in nature, so I moved them to a folder named "elegant" and gave them that prefix. I created a new set with the prefix "slats" but kept those in the main folder for now.

Added grass:
Only the black and white version and a single green. I'm still playing with a light. medium, dark for greenary. For now:
Hex #007F0E

My first wood grain effect for tiles had some large spots in them which made the pattern recognizable when using on larger floor spaces. I edited both the walls and the floor to have a more seamless style.

Initial upload to see how this all works.
