Aged Bronze Smart-Material

This is smart material I had created for my Relic Mat Project https://www.artstation.com/artwork/1nJ3Do Since it was mostly procedural mask work, I went ahead and dropped it on to a bunch of objects and polished it to create this shader and tested it in Arnold. I can't put it up for sale as of now as it relies on alot of other textures but Im planning to work on that. Let me know if you guys have any inputs. Thanks
