Ok. I admit it. This is a blast to do. I'd rather do this than eat....almost.
I began at the head and then moved down, quickly establishing the shadowed side of the jacket and the drape of the tie. Then back to the head to get a likeness and everything else fell into place. Just two pencils, white and some sort of earth color, and an eraser. Probably 75 minutes. (I want this guy's tie....)
