Material preparation: paper and pen.

Operating steps:

1, outline the outline of the mountain, grasp its size ratio, and divide the basic plane volume according to the light source relationship, laying the foundation for the next tone laying.

2. The overall layout of a large area of light and dark background color, horizontally organized sky lines from top to bottom, and the light and shadow of the picture strongly unified all backlight surfaces.

3. Leave all the light-receiving surfaces blank, and continue to strengthen the darker color areas on the basis of the tone of the dark part, so that the picture has a roughly black, white and gray relationship.

4. Continue to strengthen the shaping, blur the edge outline of the cloud and naturally overlap it into the background, and then spread a layer of transitional gray tone, and the volume of the cloud will be presented.

5. Finally, go deep into the bright and gray levels of each object, and add some detail elements in the transparent dark part to make the picture rich and natural.
