Stylized Cliff Rock - Feedback/Critique

AntlerCoffee

Hello, I would very much appreciate any feedback or critique of this material. I'm making a few stylized materials for an upcoming scene I'm putting together and I would love to know if there's room for improvement. Everything created with Substance Designer

I think it's pretty solid so far. If anything maybe a little more contrast in values and hue on the color map.
