One more example that will make you learn Blender and Grease Pencil.
Andry Douze, also known as Dedouze, is a talented artist making crazy retrofuturistic animations in Blender.
Originally from Madagascar, he traveled to Paris to study Computer Science and Mathematics, making first steps in graphics and coding.
His art focuses on combining 2D and 3D, plus adding striking futuristic aesthetic. His works are inspired by Japanese animated films of the 80s, European science fiction comics of the 60s and 70s, Moebius illustrations and retrofuturist aesthetics.
The whole process begins with the idea of the composition which he then turns into a multilayered animation in Blender. How does one create such animations, you may ask. Is it 3D or 2D? The artist uses Grease Pencil which allows him to quickly sketch his ideas and create colorful illustrations. The artist plans to release a tutorial in the near future, so stay tuned.
In the meantime, you can learn more about his workflow in an interview by Domestika. Also, make sure to follow him on Twitter.
