Once I heard about these rules, I couldn't stop thinking about them. What is most interesting to me is that 2D and 3D art intersect between these rules. This is exactly why I had to make a 3D-heavy video about this topic. Plus I have never seen somebody talk about this online so I hope you find this valuable. Feel free to subscribe or like if you want to see more videos like this.
