My result from Kent's amazing new course that can be found here : https://cgcookie.com/course/modeling-texturing-shading-a-treasure-chest-in-blender-2-8
I wish I had more time to tweak and refine the renders, but I have to call it a day at this. I had a lot of fun making it and learnt a lot about Blender 2.8 from Kent.
Win, win ;) I like the hammered reflections above the key.
