Posting some updated versions. Tiana noticed that there was a faint line around the squares. Turned out to be my shadow caring to the layer edge and creating the line. I tried to erase it but made a mess of the shadow, lol. So I copied all to a larger layout and redid. But of course I could not duplicate exactly the colors of the first posting as I had changed hue, saturation etc as I saw fit. And then I created some other rock textures for the base, so it is what it is.
