Draw the horizon line using white chalk pastel across your paper to create the snowy landscape’s base.
Sketch 2 to 3 snowmen: one large snowman near the bottom (foreground) and 1 or 2 smaller ones closer to the horizon line to add depth.
Lightly fill in the snowmen’s bodies with white chalk pastel.
Add the moon in the sky and fill the ground area with white chalk pastel.
On the sides of the snowmen closest to the moon, add soft yellow highlights to show moonlight.
Blend the yellow highlights into the white snow gently using your fingertip.
Add shadows on the sides opposite the moonlight using darker blue or purple chalk to give the snowmen shape.
Create cast shadows on the ground with blue pastels to anchor the snowmen in the scene.
Blend the blue and white pastels on the ground softly with your finger to unify the snowy scene.
Add extra details like carrot noses, scarves, top hats, or buttons using markers or chalk pastels to personalize your snowmen.
Spray drawings with workable fixative or hair spray.
