I've been away. Profile of a volcanic crater lake for L, and a light through a rain steaked window pane - hard to come up with an M but they are there. Lead light window and even less of an excuse for an N but they are there also. O is easy - inktense pencils in a grid. P is regular coloured pencil. Q is a stencil and pan pastels. Lastly R lower waist and widened with shadows using water colour. Bang on time. Whew!
