You got so many usefull comments in the topics you started in the last days.
You barely replied to the comments, you didn´t like any of them and you never said thanks to anyone
and when you wrote something you only did that to disagree.
I think you are writing a too complicated story that nobody will understand. Your brother finds
it boring, he maybe just doesn´t understand the story.
I think one constructive way to fix your story is to listen to the advice and make a simple story
first. Without a 4 member hero team, and complicated, multiple villains which are hard to explain.
You can also stick to one idea and keep the 4 heros but write one episode first where they have
to fight one villain. Finish that episode. Get critique and see if it works.
What about that?
