I saw this really awesome concept by Matt Dixon and wanted to give it a shot in 3D. This was a really great study on modeling, materials, and lighting. I modeled and UV'd the assets in Maya, high res sculpt was done in ZBrush, base material for the metal was done in Substance Designer and other details painted in Painter.
