Church rock wall

This one is inspired by the rock wall of my town church. I liked the way it's stones and grout are worked.
I've had some time to work on it and this is the result.
For this one I was also inspired by the stone generator made by Jonathan Benainous for The Last of Us:

The idea was to have an initial stone brick, fairly detailed, but not so much as to make it redundant to refine it after it's initial use in the tile sampler. That way I can have all the main shapes ready and then refine them to make them look different, since you can only have a max of six pattern inputs in it, and you can only go so far with random symmetry in terms of repetition.
Overall I think it worked well ennough for it's purpose.
Hope you like it. Any feedback is welcomed!
