USING A GRID FOR ACCURACY
For this drawing I began by scanning the original photo, adding a grid over it on the computer then printing it out. A scaled up version of the grid is then drawn by hand on a thin sheet of paper. I prefer to draw out the picture on thin paper first then transfer it to good quality paper afterwards. The advantage of doing it this way is that there will be no grid lines on the good paper and less chance of dirty smudges or indentations. I draw the design in pencil keeping it as simple as possible and concentrating only on achieving correct proportions. The faces are the most important part of the drawing so they get the most attention; every shadow shape has to be mapped.
