Batch creating Withoutta books

I'm batch creating around 20 picture books. I thought batch creating would be fast, but it's actually taking me a lot of time. I'm sort of overcomplicating the project, but trying to reel it in. Here are all my ideas. I'm going to do a ton of these different characters in the books, and each one of the characters is going to try to find something to replace the hole in their heart. I've been really fascinated with the brands like ice cream companies or cookie companies that do drops for each one of their cookies or flavors, and I'm thinking that books could be the same. I could sort of do drops like one week or do some closer to Halloween or holidays, and it all started with this book.
