Sitting Figure

This drawing is a sketch of a figure sitting in a stool, as well as their surroundings.  Some of the elements come from the drawings of Rembrandt.  The first technique used was the application of the a base layer in the water based red orange color.  Then pencils and charcoal were used to further develop the form, while crosshatching was used to develop the light.  One thing I feel that I would like to improve on is the way I use the charcoal and pencils.  Usually I either draw too lightly or use too much charcoal which is what happened in this case.  I would like to develop a medium between the two to really capture the form and lighting better.
