The design technique I applied for this assignment is Gestalt's principles of perception. The contrast between before and after deforestation. The left half of the tree with leaves on its branches on a light blue background is the state before deforestation while the right half of the tree with no leaf on its branches on a subtle red background is the state after deforestation has taken place. The transition from a healthy tree to a dead tree.
