This is an exercise in blind drawing. I began on the left, and drew the first profile. The middle person, facing away from me, was easy to draw. I took a risk with the third profile, attempting to portray the mouth and chin (unlike the first figure). Each of the three portraits has a different level of detail: the middle figure with the least; the left with a bit more and the right with the most detail.
The left and center figures go quite well together.
