Then there are four more which has a bigger role to play. When designing a character you can keep on for many hours to find a good design, but somehow it´s not until you set him/her in action that you really get to know the character. It´s the same with all storytelling ( I think ).
When you are in the "real" story and situation you get to know that character and learn how he/she should behave. It´s not so much about the shape of the nose it´s more to understand the personality.
Characters is what I like most to work with. To dive into the soul of a character and to find out who he or she is.
