Keep looping on!

In order to upgrade my skills in Blender, I followed a bunch of tutorials on the internet on how to create looping animations. I had to search for different sources in order to gather the knowledge required to create those artworks. It was very interesting because in my research I've ended up getting other tips rather than only reproducing the tutorials. Key-framing interpolation, lighting, instances, and PBR materials were part of my new discoveries.
