Debating whether I should archive this series or create a new one. What should I do?
Create a new one from scratch; if at all you have a new idea...it might be harder to go go back over something you're technically done with (unless nostalgia hit you HARD) I say do something new
What I have is a complete rewrite of the first chapter in progress.
Mostly major improvements in art and a complete overhaul with the storybeats and structure of the chapter, do you think it be worth it to create a new series in this context?
I would recommend to make a new one and leave this one as a previous work.
