This is a project by Saatchi & Saatchi IS in Poland. It’s a series of advertising/branding illustrations for Nobile Sports in Poland, and the dotted line in each image represents the pattern on their surfboards. I think it’s a clever idea and the graphics of the miniature scenes were very nice.
The illustrations were done using Cinema4D, and they modeled each element in the software for rendering and color is added later on.
