Facial features out of proportion with the rest of the face can truly affect how you perceive your appearance. Those facial features can be resculpted or enhanced to some degree to bring that particular region into alignment with others. An obvious example is a chin that is set too far back (receding or weak ) or forward (jutting). An example of the latter condition is the famous Hapsburg chin that was passed down from generation to generation in the dynasty that dominated Europe for at least five centuries. Court artists of the time clearly (and bravely) show the inheritance of that famous royal trait in their portraiture of those all-powerful medieval rulers.
