What's your thought process for making new comics? Do you have a list of characters/content you want to do in the future or does it just start on a whim?

I mentioned with the last comic, my intention was to do something completely different but I couldn't get the idea of these two hunter sisters in Odogaron armor out of my head and it just kind of happened. I plan stuff out very generally in my head, but page-to-page I just kind of wing it.
