Portrait Grid Drawing

This drawing was made by just a pencil. I started by making a grid on the photograph that I wanted to draw. Then I focused on one square at a time and I drew each and every detail. After I drew the whole portrait, I erased all the grid marks. Then, I finished by shading each part in different values to create contrast. The portrait was taken by my Ipad and was uploaded by email. On the peice, I like the way the hair is the darkest part of the portrait. The one thing that was hard was trying to make the face look real. Although the shading helped a bit, it was hard how to show the wrinkles without making the portrait look old.
