Rick and Morty House

I recently finished recreating the kitchen from family guy, attempting to make them as realistic as possible. This is the house from rick and morty, again with a realistic style. I have also included an image of the house from the cartoon for anyone who hasn’t seen it.

This project is very nearly finished, I only need to add some trees and electric pylons behind the house, and fix the roof slates (the edges and material), as well a small amount of texturing.

Does anyone have any good slate procedural textures?? and any other critisicms of course.
