Personally I give each character a face, either from a person I know who matches their personality or a celebrity that fits the description, even though sometimes it can be really annoying if the author gives more details on the persons appearance and my character doesn’t fit that lol. I’m very curious as to what other people do.
I’m the same damn way….like “oh you said the character looked like this mr author???...well fuck that you’re not the boss of me!!!”
