Start by lightly lining in the shapes and contours of the drawing. Keep your lines extremely light! A 2h or HB pencil with no pressure is good. Lay in an even tone of very light graphite on the furthest objects. You will want to tone this in with no variation or features. A smooth, clean coverage is best. You can do this with a sharp hard pencil or by using powdered graphite or blending with a tortillion. These furthest objects should almost blend into the sky; so toning the sky will add to the depth and beauty of your work. The sky is an important part of a landscape drawing, so attention to this is also important. The sky, like the rest of the drawing will fade into the horizon. Notice when you look straight up, the sky is bluer, a deeper more intense color than when you look straight ahead towards the horizon, especially in the direction of the sun.
Toning: to tone your paper, you start by using a shape pencil or charcoal and lightly cover the paper with an even medium tone. While not difficult, this does take time. You want to do this by using the point of your pencil/charcoal, and lightly rubbing in one direction, turning or rotating the pencil in your hand to keep the point. Take your time. You do not want any strokes or directional lines, but a smooth, even tone. Avoid blending and rubbing to try and achieve this, as this will work the graphite/charcoal into the paper and make it hard to lift.
