everything seems to indicate that you really need knowledge of anatomy even to know how to shade /s, well somehow I sensed it some time ago but I didn't want to see it, I watched a Stephen Bauman course to understand why I needed to study facial anatomy, it was very good, I improved my control of spatiality on the canvas quite a bit since the last time I published here, the final shading was to prove that I don't need to use references to do a simple shading, although I value the contribution they give in lighting or difficult poses. My brush work is still pretty bad so I depend on the airbrush in one way or another, I also have some control in the development of edges to communicate the transition of the shape so it doesn't look so bad
