These are from long poses, that is, drawn from a model who holds the same pose for three hours, for five days. I unfortunately missed the last day, but this is what I made in the time that I had.
It is a different process than quicker poses, one that requires more patients perhaps, but also a more analytical approach. Given this much time,
how does one go about depicting the human body in space? The body becomes a puzzle. For instance, the position, the tilt or rotation, of the ribs has to be justified by communicable landmarks; in the case of the ribs, the 9th rib is often notated as a plane shift and its relationship to other parts of the body can be important leads for the eye to follow.
