Box and Sphere - Vilppu drawing manual chapter 4

In this last chapter I drew figures out of boxes. In the chapter before that, I drew figures out of rounded shapes. In this chapter I combine the box and the sphere. The box representing the pelvis and the sphere representing the rib cage. I did this with drawings of people in the park. Unfortunately the studio where I do longer studies has been closed. So, I was not able to do any longer studies. To bring home the concept I decided to do a very short animation. In order to make the animation work, I really needed to understand the concept in three dimensions.  All studies done on sketch paper with ball point pen.  Animation done in Toon Boom Studio.
