Here's my latest video, which shows how I created Winter Trees, an acrylic painting which is part of my Birkenhead Park series. The painting is based on a sketch done on location. Over the last seven years I've built up a pile of sketchbooks crammed with ink and watercolour images of the park. I enjoy sketching outdoors. Usually my dogs are (impatiently) keeping me company. They wait while I draw, gradually tugging more and more on the leads as if to say, "Hurry up will you!" So I'll quickly dash off the latest sketch and then we'll walk a bit further. Often it'll not be much further, as they promptly skid to a halt to sniff the next fallen leaf or twig. "Did you really need to sniff that with such urgency?" They reply with wagging tails and eager sniffing. Apparently not all fallen leaves are equal.
