Haha, nice wordplay! And very cool sketches, @Michael Mendiola! I suppose you didn’t post this as a critique request, so excuse me for maybe being nosy, but it just occurred to me if you have considered taking the simplification even further, like really geometric, as a way to focus mostly on the joints’ functions and on the bone’s most basic forms possible. Stan and Marshall propose this kind of approach in The 6 Types of Joints lessons and I thought it might help complement what you already have going on in terms of studying the bones. Just a suggestion. Keep up the good work!
