Create a split-image of the same light skinned 21 years old Ethiopian man shown

Create a split-image of the same light skinned 21 years old Ethiopian man shown side by side against a messed up old wall background to illustrate a before and after transformation. In the 'before' image on the left, depict the man as shorter and wearing a plain white T-shirt and jeans. In the 'after' image on the right, show the same man taller, with no change in physique, wearing the same white T-shirt but with casual pants instead. Both images should have the man smiling and looking directly at the camera, with a noticeable difference in height and presence. The background should be minimalist with natural lighting, highlighting the transformation. Make the picture realistic
