Hi! Well, in my opinion, nothing replaces common sense and logic. It is the first guide that allows you to know if what you are writing is inside or outside the parameters. You should consider a story or a novel as a letter to someone you love. That will be your ideal reader (IR). In fact, it is based on this that the thematic orientation later arises; which is divided, yes, depending on the treatment of a subject and the potential IR, in M, MG, YA, A, etc.
But even in an erotic scene, ice will always be ice and the fire, fire. This aspect, which has more to do with logic, in greater terms requires that you always keep in mind the coherence of your story, that there are no contradictions in the dates or characteristics of the characters: if you said that your heroine has blue eyes, later you cannot appear saying that it has them green.
You have to be very careful with that, because it happens or it be ignored even to beta readers. By extension, another of the most serious problems you may encounter will be the famous
Deux Ex Machina. The rule of Chekov's gun, come on.
Deep down I'm telling you that
the first best reader in your story will always be yourself; it must have happened to you, I imagine, that while you are ordering the children's room, you suddenly find an old box lying around and inside a forgotten manuscript, and when you take what at first was a simple glance, when from the first floor your mother or your husband is calling you to come downstairs, you have just realized that you have been reading that old text absorbed for ten minutes, sometimes even in wonder, I dare say.
This is one of the main reasons why it is recommended that the finished texts should be allowed to rest for at least a couple of weeks before being read again. Since that time has passed, you will have been doing other things in the meantime; then you are much more clear-minded and fresh to face a revision. In fact, Stephen King in his book
On Writing recommends six weeks.
With which it is deduced that it is not advisable to let others read your texts until you have made that first rereading alone. What happens in this part of the process is that your mind is no longer creating as in the writing phase, but is reviewing, and is saying in your ear: "hey, here's a character motivation problem", or " Wait, I mean, at what point did someone say that this or that thing was going to happen? ¿From where appeared that gun wich the hero killed the villain?" (
Deux ex Machina) .
Therefore, it is important that you take note of all those concerns that appear to you. This will generate a questionnaire that will give rise to a new creative process.
But calm down. First of all, do as many closed-door reviews as you deem appropriate. That, as I said, generates a valuable list of points to correct. But just that.
Do not correct anything yet.
Because now the time has come when you can deliver the text to your beta readers. People of trust. Friends, if possible. You will see that some of the opinions of these match your list. Or new things will appear that no one else has seen. Write them down and add them to your list. But only you know who is right or wrong. Look for the repetition of common patterns. Stephen King recommends eight beta readers; in fact, in the book I cited, King develops this and other themes in a much more didactic and better way.
Hope this help
