Some Assembly Required - This Comic Book Manga Puzzle Defies Me

I know I've done a lot. And I know that I have many talents. But my art-stories need to make more sense than they do. I've written a lot of stories, drawn a lot of comics pages and illustrations. But it lacks cohesion. It was meant to be one cohesive unit of storytelling. And it's not. My artwork is fragmented. I was planning on placing it all together, but it didn't turn out to be that easy to figure out. I couldn't figure out how to combine the architecture into scenes with the characters. I grew up assembling things in my room, like race car sets, and domino rallys and capsellas. Since I work so well with systems, I thought the system I built for myself in my production design and character concept art would make it easier to build a series of comics compositions out of it. I thought building rooftops separately from characters heads and bodies would just make it easier to composite them together later. Like approach it scientifically, like building a machine and assembling it from the pieces I already built, but alas, it turned out to defy that. I couldn't figure out how to make the pieces fit together.
