A Quick Demonstration of my Method

This is the face I will draw. I will draw with a pencil.
STEP 1: Using sighting I begin by making a few light marks which establish the PLACEMENT. This is done carefully to make certain that it is correct. 
STEP 2: I draw the simple contours of the features.

STEP 3: Using sighting, I double check their accuracy by comparing them with the model.

STEP 4: I refine the features somewhat as I block in the shaded areas of the face and hair.
STEP 5: I refine the features further and develop the shadows.

Total time: 30 minutes
