I want to create a transition in the middle of two images. The image on the left must be an extremely sad businessman, depressive, jaded, you can clearly see that he is not happy despite having a lot of money, he is in an office with an extremely dark and bad environment. In the image on the left I want this same businessman happy, with family, enjoying quality time with children and wife in a home with a bright and welcoming atmosphere. IMAGES MUST BE AT DIFFERENT TIMES, MONEY SHOULD NOT BE IN THE IMAGE ON THE RIGHT, THERE MUST BE TWO BUSINESSMEN, ONE ON THE LEFT IS SAD AND THE OTHER ON THE RIGHT IS HAPPY.
