life model drawing short pose female standing, Center line (below)
Instructor spoke about the use of center line with landmarks. This was very useful because this explains how we can deal with models moving. If we use a good amount of time checking and marking a line that goes through the entire pose, we capture the gesture of the pose. The envelope can then be corrected with on a good basis. We can be more certain weather there was a change of pose or perhaps we simply didn't get the pose right earlier.
