Dude... Writing is hard. Why is it this hard?

I don't know it's probably more of a me thing but writing is kind of hard. I especially struggle with writing world details because they somehow always feel as if they were put together with duct tape and spit. Maybe writing the worldbuilding details on the side as I write my main stuff would be much better for me? If you're wondering, this talk is for my little passion project Legatum Invenire (Check out the main three's design!) which I'm now sure it's gonna be a comic.

I've laid out the first 3 Acts of the story. You can think it as seasons of a tv show. It's there to help me clear what will be the main focus of that specific part of the story. I'm currently happy with what I have. I'm also trying to "study" art better because I need to be better at art if I want to to do this thing which is probably the most soul draining part of it for me because studying is never fun and to get better at something, you have to endure mediocrity first. I just hope I can keep it up and something comes of it. The hot ass weather isn't helping with any of these ugh... I literally need to learn to draw humans because one of the main characters is going to be a human but it's not just for that, I need to be better at gestures and expressions so the comic doesn't look stiff as hell. I hope I can make something that people will like and appreciate at the end of the day and even if no one is, I can say I at least had fun.
