I think you are talking more about the quality of the writing so I will change your question.
When do I think the quality of my āstory makingā got good.
I have been making stories since I was 9. But I only started writing at 15.
But I think my storymaking didnāt get good until I was 14. And Iāll tell you why.
I had a wonderful story that I had thought over and thought over every for 5 years. It was my first story. It was big and beautiful and original! But guess what. IT WAS SHIT!! Ya wanna know why? It didnāt make any goddamn sense! The characters were aaawwwweeesssooommmee but the plot of the story didnāt make any sense! Iām not even sure if there was a plot by the end of it:/ Also there was this weird power system that was barely involved in the actual story. AND IT WAS JUST A HUGE MESS!! But luckily! I realized that my story would never be able to come out of my head, onto paper, and then be translated by another human mind, into the story again. It was just an impossible mess.
So I had to do one of the hardest things I have ever had to do. I had to erase it from my mind. I had to abandon that story that I had loved and worked on for 5 years. It took awhile but I did it.
And so when I was 14, after I had freed myself from the first story. I was able to understand what made a good story. And also I started learning a lot about how to tell a story. I had learned a lot of creative skills from that mess of a first story. So once I had learned to tame my passions, I feel I finally became a good story marker.
Everyone is different, but this is my story. But honestly. I feel itās mostly just talent when it comes to writing bruh:/ Either you got it or you donāt. There are ways to refine it; but you gotta start with the meat and potatoes.
Edit: As far as my writing my current comic. https://tapas.io/series/CrimeandCars I think the end of chapter 1(not yet released) is where things start getting more to where I want the comic to be.
