This is how the real president should look like
Here's what I did:
*used clone and scratch remover to clean the face and make him look younger
*darkened the hair and cloned it
*enlarged left eye, copied it, fliped and pasted right
*Copied and pasted parts of nose (with rotating) to change it's shape
*whitened the teeth
*smoothened the face
*added noise to the face to make skin texture realistic
*adjusted contrast, color and gamma
