As an animator i done many different animations, some creating the visual to the story of others, some adverts etc but all with characters created by my imagination, but then in my private animations i started to play with creating famous characters like Superheroes, that really can have any type of face, as long Superman continues to have blue eyes and black hair anything else is ok for interpretation.
So slowly i started to introduce real life characters, like Donald Trump, Sarah Sanders and more, maybe because of those i started to attract Podcasters, You-tubers and Comedians which wanted animated versions of real celebrities they were voice impersonating and some just a animated version of themselves for an intro or even a real or fictional story with themselves as the main character.
