THE STEPS TO DRAW " YAAKOB, BLIND MUSICIAN"

Ok....i putted 3 pictures here....most of the drawing artist might start with , giving a tone all the figure...but for me , i must complete the face part first..why?because....it will give me a courage to continue draw....drawing need to be patience and higher concentration...but, it doesn't mean that someone have to follow like the way i draw...each person have different way...and for me..face of the subject should be complete first.
