"If you are writing about ethnicity, pick a name from the ethnic group."

This is where a lot of Nigerian writers on Steem lose my attention, I'm sorry to say. If I were to stress that any further, I'll add the appropriate use of images to push the story. I see many African-set stories using photos with places and people inconsistent with the story. No photo beats inappropriate photo every time.

I totally agree with you that character development is integral I'm crafting a good fiction story. While I wouldn't use "clone", I echo that taking after real life characters is a useful tip to have in the trick bag. You don't want Aunty Aisha who picks her nose to identify herself in your "fiction" story. Lol.
