ARTIST Tim Leeson's Improvisations exhibition is running at Natterjacks until November 25, and features new pastel drawings alongside some of his abstract drawings and paintings. Tim's interest in early 20th Century art is evident in his latest works that are created in a loose Cubist style with the theme of Fish and Triangles prevalent in many of the bright and cheery drawings. Tim says the fish describes his spiritual side: "The triangles I think are symbols of my love of music. My late mother Jennifer also taught the piano and I see my triangles as metronomes."
