This is just a verry quick Work i've done for a Demo, with one of my favorite Cars. Without Dirt and Scratches on the Textures. The Backplate is made of some shots in Swizerland and Germany. The Car and the Rendering is done in Cinema 4D r17. The Fog, Snow Bluring and Backplate Composing is Photoshop.
If You like the Backplate you can Download it Free for Private Use in
