I don't know if I can do different textures for the top of the dirt pillar. The problem is, I can't make a copy of the texture, it may cause some legal problems or things. But I can try, it's something easy to do. Same goes for the stone stairs, and as for the olive leaves, I can edit them and make a new leaf texture.
Thank you a lot for getting interested in my mod, this is one amazing thing.
PS: And yes, the olive and stone slab things are intentional. If you really need to have a different texture for the smooth stone stairs, I'll make it that way.
