The process I would like to undertake will allow me to focus on finding out how personality traits work and how they are given to characters, I'm sure there are books on semiotics that specifically talk about personality traits in stories. Once I find information about personality traits I will depict the semiotics and try to explain how they work within a story.
books I can look into are:
Richard Williams (2009) 'The Animator's Survival Kit'
Propp, Y.V. and Scott, L. (1968) Morphology of the folk tale. Edited by Louis A. Wagner. 2nd edn.
Su, Haitao, and Vincent Zhao. (2011) Alive Character Design. 1st ed.
Crossley, Kevin. Character Design From The Ground Up. 1st ed. Ilex Press, 2014. Print.
Thomas, Frank, Ollie Johnston, and Frank Thomas. The Illusion Of Life. 1st ed. New York: Hyperion, 1995. Print.
An animation I will be looking into is "Kimi no nawa"(your name) as it is a great example for personality traits studies.
Shinkai, Makoto. Your Name. Japan: CoMix Wave Films, 2016. film.
Since this film is about body swapping we can see how each character reacts in the other's body and how they have to interact with the others life.
