I'm currently only a PC Tapastic user.
Hmmm, your setup is a bit different from what other artists are doing on Tapastic. Like how you've posted a Cover, Title Page, and Prelude, each in individual episodes. All three of those could probably be lumped into one episode to make it feel more like a substantial post. A title page may not even be needed here since it's online comic. All the info on a title page can go into the comic description where you currently have,
"outstandingpajamas.com
This is the story of the Altus Libera."
[You can also tell the readers what they're getting themselves into here and tell us what the story of the Altus Libera is. What story genre is it? Who the main characters are? What's the conflict? How ofter will you update?]
To be honestly, episode Clubhouse Vigilantes, was the only episode I actually really looked at because the other episodes felt like fluff filler. Where does Clubhouse Vigilantes fit it with the spoofy daredevil and punisher superheroes? Is there a continuous storyline or is it a collection of random stories? Right now it's hard to tell.
Tapastic, currently supports animated gifs (see comics like Bog Girl for reference). Maybe instead of posting pages to get people to go to youtube (as a reader I'm very unlikely to click these links), you can make pages with embedded animated gifs. Seeing an animated gif comic page would probably help increase the chances of people clicking the youtube link in the description to see it full animated. This is a comic site after all. People here are looking for comic pages and not youtube links.
It looks like half the work is already done, though. The animation looks great in your youtube videos. You can turn a couple of those animated scenes into gifs, panel them vertically, add back in dialog bubbles, and that'd make a very kickass Tapastic series.
