This is my first completed car render. It took me a few months, I did the modeling in a couple of weeks, then took a long break, and came back to finish the materials and rendering, which took a while on a laptop and rendering on CPU. I used blender 2.78 to do the modeling, and when I heard about the Principled Shader, I decided to use blender 2.79 to render it.
Even though I won’t be touching this project again, any feedback and criticism would be most welcome!!!
Thanks
