So after trying to use it for little while, I've notice one thing. I think the default "layout" of the tiles by default is a little strange. I'd recommend reorganizing them in a more seamless way (example below). I struggled with grass, as some of your examples show simple grass with little to no detail other than small grass blades. But your tilemap made it a tad confusing where the tiles were. structurally, it would help newcomers to organize them a bit.
It's a very good tileset nevertheless!!
