d) Use a combination of hatching and cross hatching lines to shade in the general weight and volume of the hand.  Note I filled it all in as I intend to remove some shading to create light.  I also left in my previous guidelines as I will incorporate these as I go on.

e) From here using a series of graduated shades with a 2b applied with light or heavy pressure I apply more sophistication to the drawing.  To soften some areas I rub in the pencil with my finger. Also use a little water, it strengthens the darks.  Using a rubber I remove some shading to create light.  This creates more textural drama and volume as well as character.  Doing studies like this is a great way to improve not only your drawing but also your visual observation which in turn will enhance your painting.

Until next time, enjoy.
