In this video I develop my urban sketches into watercolour thumbnails images to help evaluate colour and composition working on 4 images at once! The sketches were drawn as urban sketches in my Lockdown sketch book on a visit to Saundersfoot, Wales. The thumbnail paintings are approximately 2*3 inches in size and are offcuts of random watercolour paper. I use a split primary palette of warm and cool colours – Permanent Rose, Windsor Red, Ultramarine Blue, Cobolt Blue, Quinacridone Gold, Windsor Yellow.
