This one is just when the author brings in too many characters than the reader's brain can handle.

Chapter one, the author introduces Nkechi, the main female character, then introduces, Funke and Mariam, Nkechi's best friends. Then we still see Emeka and Michael, the popular boys in town, then of course, the antagonist, Esther shows up with her own friends, Fie and Ene, the class clown Ebuka and Soji, the perverted teacher all in chapter one we get this characters. And it doesn't end here as they keep on introducing more and more characters, characters who have no goal in the story.

I read somewhere that this characters are like ants on a sidewalk, we make note of them, but we definitely don't need to give each ant a name and a backstory.

Inconsistences are huge flaws in character development, for example, in one scene your character is sweet, naive and kind and in the next she is a sassy, I-don't-care-girl. It's just like a book [I always make reference to this book.]

The author had spent the first chapter trying to get her readers understand the character, from that, we got that she was a really shy person, she likes to stay on her own and read books, she doesn't like violence and she wishes unicorns were real, a really cute character. The next scene, which took place at school, we see this character being approached by a boy, they get in a conversation and then she openly flirts with him, and all the shyness and naivety was gone. And I asked, "I am sorry, isn't she the same Elena in chapter one?"

Q: What happened to Elena?
A: Nothing, she was just replaced with Sabrina.

This mixed personalities confuses the readers and annoys me. The author to stick with the personality of a character and stop mixing it up.

The bully can't suddenly like the bullied, it doesn't just happen overnight. If it going to happen, it goes by slowly and the author should explain the events that led to this.

Also, some authors tend to make a perfect life for their characters, I just wonder if anything bad happens to them

Elena was about to fall down face flat, but no, John was there to catch her. [I want her to fall, let her fall and break her two front teeths 🙂] When we all know in real life, it hardly happens.

Bring out realistic events that people can relate to, it helps your readers flow more with your characters, and that brings about a good reader and character relationship

Ok, let's move on to the POV's

There isn't much to say on this, I won't really waste time ranting here.

If you're writing a book, not every character should have a POV. Remember what I said about the ants on the sidewalk? Exactly. Limit the POV'S to just the important characters and don't change POV'S in a chapter unless it's completely necessary.

I usually do chapter by chapter, switching the POV'S between my main characters, you can do that also.
