I draw, and the first full chapter I did took like, a whole year to do. It was 60 pages in total. Which, to be honest, was longer than I wanted. I should have split the first bit into a prologue. To be fair, I wasn't consistent in drawing at the time, and I took about 2 and a half months combined of hiatus's throughout. My 2nd chapter is almost done, and it should end around 50 pages in 5 months? Though, I do long form, so an average page only has like 3 to 5 panels on them. So it's hard to properly consider them individual pages. I usually update 2 pages a week, so that would make my chapter end at closer to 25 pages, if you consider how many I upload at a time.
Okay, now that I've officially confused you. Have a nice night.
