if its only one word i'd say Perspective.

The artist used the perspective to show depth and create emphasis in this painting.

Explanation:

The linear perspective system projects the illusion of depth on a two-dimensional plane by the use of “vanishing points” to which all lines converge at eye level on the horizon. In the case of this painting, the artist used a vanishing point formed by the horizon and a group of parallel lines that converge on the center of the canvas. Also, clouds behave in the same way, converging to the center, distorting its form.
