This class is about using a few simple rules about one point perspective while maintaining a loose watercolour style. We'll take a look at moving vanishing points and horizon lines using four different scenes. The idea is to sketch minimally, paint quickly and not over think the subject.The class is broken down into simple easy to follow sections so that you can pace yourself and enjoy the process.
