I had the basic plots for the story in my mind a long time, but when illustrating/writing it, the ideas just continued to grow. There’s a lot I would change now and make NMT a lot darker than it is. I have a scene I’ve had written out for a while for the opening, which is a lot darker than the one currently in the comic. (One day I’ll animate it hhaha). As for the second one, I’m guessing you mean the origins (as Endermaretale is a collab and for fun), I guess I wanted Chara to have a deep intent for her hatred towards humanity, and seeing as child trafficking and sexual slavery are pretty heavy topics that people are desensitised about, it’s just important to address such things as they are real in life and do effect people’s mentality and physical health.
I love character growth, and having written Chara’s past and where she came from and how she developed in NMT, I am honestly fond of her the most as she’s growth so much from where she began.
Idk. I guess make sure you have passion for your work, enjoy what you’re doing, see different insights and perspectives, and tell a story.
