My three most important characters, including the villain, have complex backgrounds that go before the protagonist even met their friends. I and some of my friends have gotten around to sharing our stories with each other for critique, but I don't really know how to share it with out taking the time to sketch some visuals or risk spoiling the entire plot I've put together. Especially when it comes to the fact I need critique on them but the past they have doesn't come until later in the story. So my question is, when talking with others about your characters, how much do you tell them and how much do you leave for them to figure out? The only way I could think of so far is just sharing a script with them on docs so they can leave notes while I'm working on it.
