The Human Butterfly

I consider myself fortunate to be a teacher assistant to Randolphlee McIver, one of the best, if not the best, figurative artists today. His knowledge and expertise in anatomy is nothing short of spectacular. Based on Randy's notes and sketches, I composed my own replica of the pelvis, all based on his calculations. Randy set up 6 points on the pelvis:

1-Anterior superior iliac spine (ASIS or front point)
2-Wide point
3-High point
4-Reenting point
5-Posterior superior iliac spine 
6-Inferior superior iliac spine 

Displayed below are step-by-step visuals of the pelvis. The initial portrayal showcases a simple, symmetric block, capturing the essence of the pelvis's form. The six points mentioned earlier are visibly marked on the clay, facilitating precise measurements for accuracy. With each measurement and meticulous removal of clay, the intricate details of the pelvis gradually unfold. The medium used for this is oil-based clay, known for its non-drying properties compared to standard clay.
Along with the pelvis sculpture is a handy ink sketch to tie everything together.
