Substance Designer Tutorial - Creating Aging Bronze

Hi there! In my own journey of learning Substance Designer, I stepped out of my comfort zone of recreating tutorials, and made my own. By no means am I an expert, but I was happy with what I was able to learn, and hope to share that with someone else just like me - wanting to learn this super cool program. Here, I explored how to take a rather simple material, and create controls to widen its potential. 
I broke down my process step-by-step, but I do assume you know some basic interface and navigation. Other than that, it's relatively beginner friendly.
You can access the tutorial here:

Enjoy! I hope it's helpful ^_^
