The first step is picking a nice reference. This picture is originally in colour, but to make it easier I turned it black and white. I usually print the reference, but that is not necessary. In this drawing I used paper, a tissue, an eraser and only one pencil. I only used a Bpencil this time, because I know that an 8B pencil (or any pencil like that) isn't always withing reach for many of you. But I do recommend using more than one grade, to get better realism
