This is the buildings volume and the one that fixes the most common glitch. It’s all about perspective, finding eye level, one and two vanishing points, how to draw a street that runs uphill, how to fake a crowd of windows without counting every one. Then texture — brick, glass, corrugated iron, wet asphalt — and how to decide what to leave out, which is a lot of it. The chapters are short, with his sketches next to sketches from other urban sketchers, and a lot of before-and-after showing where a drawing went wrong and why.
