Hello, I modeled this robot by referencing one of Burak Kiyici's concepts. You can see the pen drawing of the robot. Also Burak's portfolio is here: https://www.artstation.com/artist/burakkiyici
I used nurbs modeling tools of Solidworks, unwrapped in Modo, painted with Substance painter (painted so many normal maps) and rendered with Octane Render.
I hope you like it.
