Drawing
Shading is the darkening or coloring of a drawing with lines or blocks of color. It can be used to make your drawings more three dimensional. Shading is the process of adding value to create an illusion of form, most importantly the light in a drawing. It should have a highlight (where the light is shining), mid tone (goes darker in color), Core shadow which is the darkest color on your drawing, then there is the reflected light. Reflecting light is where light shines on the object you are trying to draw
