First twenty-nine drivers, sketched from the passenger seat while overtaking on the motorway. Their faces were only glimpsed in passing, so I had to quickly memorise the key lines, but they were always in full profile which helped simplify things!

Then nineteen pedestrian bargain-hunters, seen while I sat outside a cafe in Bath. With these faces I usually had the luxury of several seconds as they walked past, so one or two even look like their subject… For both collections the key lines were drawn with the inevitable brush-pen (this time the #40 with longer sable tip), with shading and colour added later. I’ve learnt that noses often just need the shadow below them, and that I need to tone down the lower lip shadows that appear on all the faces, they’ve become a habit!

Lexington grey in Kuretake #40 brush-pen and water-brush, water-colour, A5 – about 1 minute per face?
