I think one of the main thing we can see if we let say study leonardo is the focus on the feature.You see how he use contrast to show the form yes everything as not to be defined.Art is also about drawing less and giving the illusion and let the viewer fill the gap.

Tips:If i am correct he seem to smudge the line to indicate is form instead of hatching to show form.
