You have got a bunch of great feedback so far, my small addition is that I think that you did well with your first draft using the tri-fold “Shape” to boil things down and recognize what is important, now that that is done i think this clearly should be expanded a bit… i think you could hit a 16 page zine with very little effort on this idea. Don’t get me wrong you still want to constrain the idea down, hit the most important things certainly! but now that you have the knowledge it will guide a tailored and refined Zine.
Good luck with whatever you decide to do! and know the discord community will be here to give feedback along the way!
