It probably is slightly egotistical lol but I do it too. Yes haha
Sometimes, I'm so close to the material, completing one page at a time per week, that I lose the big picture concept of the chapter. I script out the full issue before drawing the pages. So when I'm working on each page, it become kind of a mechanical task of just drawing.
Revisiting and reading through the whole series is a great reminder of what's been accomplished so far, and how the story has grown. And I honestly enjoy my story and characters.
