Cobblestone Stylized Material

Cobblestone material for the stylized material series I'm working on. I imagined this floor on any kind of dungeon or gothic street/area, I really like the purple and violet tones I used for it💜 but I also added some variations to see this floor in different types of dungeons or lighting.
There's only one breakdown since both floors are made exactly in the same project, the only change is made in one of the initial nodes which makes the shape of the tiles different.

The showcase environment I used for demonstration is Stylized Paris Street from Fab https://www.fab.com/listings/abbaf1ea-b98b-4e96-8ee8-daeb241a1377
