These were Bionicle G2 Masks that I modeled in Blender a while back in early 2017. This was when I was starting to experiment more with blender and I got more comfortable at 3D modeling. Don't really have any plans for Bionicle now since I'm learning a new version of Blender, version 2.79, so I don't know if I will ever model or animate Bionicle again.
