What You Can Work On Now for what you can work on to become a professional model. Facial expression, posing, make-up, hair styling and wardrobe are items that you can practice on your own.
People talk about models spending a lot of time in front of a mirror.
After you get past your genetics and business professionalism these become your modeling tools. By honing your skills in these areas to perfection and combining them in creative ways, a professional model is produced. In the old days of melodrama and vaudeville they made a science out of communicating with facial expression or body position. They exaggerated and standardized every emotion that one might want to express. They produced books showing these standard expressions and poses and when you studied theatrics this was part of what you learned.
