Drawing Alter Ego Ideas

Alter Ego

1) the opposite of who you usually are and your presonality (e.g. a hippie's alter ego would be a fascist dictator)

2. the bad side of a person that may come to life at anytime, switching your personality (this is fantasy, though some people may believe they have an alter-ego in which they can't control).

3) A person who you aren't ut you act as sometimes as though you have transformed (e.g Eminem's alter ego is Slim Shady)

I want to do a painting with my alter ego like the black swan
