A little process of this drawing.
Then with a charcoal stick darken the areas of shadows for later fading to have the ilusion of skin.
Here I started faded the charcoal with a little brush and the tip on my index finger to start gibing the piece more volume
Here if the finished portait as much detailed I could give with my charcoal stick and my erarser to give it some light.
This is the reference photography I used to draw this piece.
