Here are two of the many Bath buskers. The first is Ben Powell, an impeccable finger-style guitar player who I’ve sketched a few times before (see below). The weather’s been fine so he’s barefoot this time. I showed him the sketch and got chatting; his love of guitar started when he heard John Williams as a child.White Gelly Roll pen, Lexington grey in fountain pen and water-brush, watercolour, A6 – 20 minutes

And here’s Steve Robinson mid-song; apologies to him for the mess I’ve made of his face. I spent most of the time concentrating on the tricky hand angles; then I tried to correct the mouth and the problems escalated… Beware of over-working any part of a sketch, but especially the face!
