My First Substance Material - Medieval Bricks

I knew if I really wanted to branch out and improve my skill set I was going to have to learn Substance Designer. This is my first real material of my own! Using the instruction from Ben Keeling over at CGMA, I feel like I have a handle on the fundamentals enough to really experiment. He explained not just how to accomplish a brick material with what nodes to use, but how the nodes behave and that is what led me to this material.

I wanted to deviate from the standard brick material because I wanted a challenge. So I chose to do this stone bricks from the Medieval era. I hope everyone likes it!
