One can never do enough block-ins. It's funny, prior to having joined the Georgetown Atelier I never heard of the term block-ins. I'd have just called them drawings. But alas, the block-in is really a different creature. It's the scaffolding upon which a drawing will go. Much like the blue print for a building, only here you construct the drawing right upon it. So there are faint construction lines and directional lines and tiny angular lines and sketched in fuzzy core shadow lines and even a light tone washed upon the dark side. I being in love with contour can seldom resist to resolve my block-in lines into a final, finessed contour. The ones below I left more block-in like.
