For a while, I've been wondering how to create efficient user persona. Asking myself, if it needs to be super real info or let your imagination work a bit creating a certain type of personality.
So the question is: 'Are you using realistic images for your personas? If yes, what are pros/cons of this approach.'
'Or you use illustrations? Maybe, specifically created for the particular project like this one https://dribbble.com/shots/2722765-Freebie-Foodly-Avatars ? If yes, what are pros/cons of using them for you.'
Looking to your opinions on this matter. Thanks.
