Live Painting Demo
Painted this as a demo on how to build a generalized landscape. It was created during my Beginning to Intermediate Watercolor course at the Perkins Center for the Arts. 

The technique of not painting to the edge of the paper helps beginners fit all composition elements on a page. The painting can easily expand to fit reflections or tops of trees that would have been cut off by the end of the paper. Of course it is important to learn how to properly plan a composition, but this is a great stepping stone.
