Lots of helpful and reassuring comments here. I'm "serializing" my comic here on Tapastic. It was originally never intended as a webcomic, but rather a comic that could be published on the web. The intent was that the reader consume it in one or two sittings. Initially, I put all 44 pages up at once on Tapastic, looked around a bit, and realized that:
1 - That's not really how things work around here
2 - Because of the format of the website (vertical scrolling), asking the reader to scroll through 44 pages of dense art and copy is... not wise.
In the end I put up the first 6 pages. I think there's a natural break after the first 6, and I believe most stories have a cadence or rhythm to them, you just need to find them. I've already plotted out my next few updates, breaks in pacing which naturally occur every 2 or 3 pages.
Of course, I could be completely wrong and it's possible trying to adapt my book to this format simply doesn't work!
@baroquezombie, agreed, Understanding Comics is an incredible book, every artists and comic book writer should read it!
