if green yuri is THIS popular and big with just 4 pages, imagine the power of 20
Sometimes less is more, and too much would lose the charm. That being said, i think this could safely add 50-100% of the current pages to flesh it out. As it is, it sometimes feels like the chapters don't have enough narrative keyframes, figuratively.
I think it works pretty well as a twitter comic, honestly, the scene-vignette style of it is interesting and it's easy to fill in the gaps as you read through it. But it does kind of hinge on the reader being aware that it's being released in 4 page stints.
When I read the published book form, I often find myself wondering if readers that discover it that way don't find it oddly disjointed, since there's nothing that indicates when one chapter ends and the next begins. If you're not aware that it's being published in 4 page groupings, the way the story seems to lurch forward every couple pages must feel kind of awkward.
If I were involved in publishing it, I probably would have suggested putting the publication dates on the first page of each chapter, to help communicate the format to new readers.
