Inside the forms. I am attempting to draw attention to the importance of building three dimensional form through thinking of a volumetric subject and not outlining a figure. Volume is communicated through the involvement of line around and on top of the forms we develop. This is again a restatement of the early principles of form intersections, wrapping lines, and overlaps.

I'm drawing the connection on the left side at 10:21. I'm thinking of this line as an "S" even though its longer and thinner. If you see a "C" curve, that's fine, but my intention is to organize specific lines to represent the pinch v stretch. At this stage in the drawing the core masses (shapes of rib cage and pelvis) are dominant forms which my connections (S=stretch and C=pinch) are attempting to attach to (this is a continuation of the earlier lesson on form intersections). I'm using the idea of a dominant form to help call back to that lesson and make the emphasis on the idea of line to build continuity with the egg shapes. This is done here through "T" overlaps and wrapping lines. This has nothing to do with the hip v the flank. It's more about how I'm thinking with the language of line and drawing. Hope this helps to answer your questions.
