How important is it to assign a real face to my character in my writing process?

 

It's not crucial, but if I can have it, why not? In order to do more ‘show’ than ‘tell’, I need to be able to translate the character’s body language, facial expressions, the way he/she speaks into words. I always find it helpful to have an image/a face ready in my head. 



I normally start with celebrities.
