Even so, it is possible that in the future problems will arise that bother you, for which I would advise you, and it is not about making a diagram or plot, but about being prepared to answer the following questions. The problem I see has to do with the maturation of the writer. Even if it is your first book, some are aware of this process and it frustrates them not having considered these things from the beginning, and although it is obvious that the answers that each of us find may not be the most adequate or correct, at least they are sinceres, they are what we could do best with what we knew and the ability we had at a certain moment.
This is what allows us to say years later, "okay, it was the best we could think of, an honest attempt" and therefore makes us look at that first literary creation with affection instead of being ashamed of it. It allows us to continue growing. In addition, these questions have a double utility, since they allow the writer to set objectives and correspond even to a first form of self-programming: the mind begins to propose tasks and works according to these, at an empirical level, once the field already it has been outlined, has a a map on which begins to act.
I mean questions or aspects like these:
What is special or different about my story?
It is such an obvious question that one as an author does not even ask it. Come on, that novel is like our son, what matters to us is that it "be", that it is born, we know that we are going to love it the same way.
But in a convention that question, asked by a nerd, has a completely different and even aggressive look that we feel as a personal attack against us. And yet an editor may ask you exactly the same thing, so be prepared. I don't think they care much about the Anxiety of Influence that the beloved Harold Bloom talks about, which gives a more spiritual character to that need to create something different. What interests them in terms of the market goes this way: why would a reader choose my book over so many others? Because of the battle scenes, the sex scenes? Be careful, there are many elements that make a book marketable and without a doubt the best are grouped around literary issues, by the type of story and what is told; but there are authors who are characterized by the creation of worlds, others create unforgettable characters, others simply have a storytelling style that is novel.
But there are others that stand out from the rest because of the general concept behind the story. It has to do with positioning theory. The point is that if you manage to create an attractive type of MC, a kind of Batman, Conan or Solomon Kane, it is as if you have a movie star for whom you have to write the stories; not the other way around. It is obvious that a miracle of these characteristics will not be seen by most of us, but nothing prevents us from thinking big. Get used to thinking big. One guy in a studio has a problem putting ten thousand guys slapping each other with other ten thousand. But nothing prevents you from talking about a hundred thousand per side actually doing it. Or imagine magnificent battles of gods in the best style of Zelasny.
Other ways to ask yourself this question are:
What other stories does mine look like? Is it a copy of another?
Is the influence of one author or another very noticeable?
In creation, it is often said that the work is 70 percent reflection and 30 percent execution or realization of it, so the time you have spent thinking is not wasted time, somehow it takes you to a road. The important thing is that you trust him but also be attentive to new reports from your mind. Sometimes your brain gives you the best idea even in dreams.
My best recommendation is that you take a look at
