Grand Epic Elemental has been up for nearly a year (started mid-Oct 2023), and I just started posting the reboot two days ago.
For the original comic, I initially updated multiple times a week with shorter episodes, then slowed down the update frequency to 1-2 times a month and increased the episode length as time went on (also improved the artwork a bit). The view count drop-off after March was due putting the comic on semi-hiatus while I worked on the Last Train comic contest. The last update to the old version of the comic was near the end of June.
I'd been collecting feedback on the comic over time and decided to reboot it to address the issues with slow pacing and artwork not being polished enough. Also decided that if the comic was going to be rebooted, I would make the whole thing full color (the original comic was only in full color for the first three episodes before I switched to B&W), which meant that updates would probably not happen that frequently. I started working on the reboot in late July, but then put it on the backburner because the Action Fantasy Tourney started, so it took a while before I finally finished the first episode.

Reboot (Daily view counts)

It's only been two days since the reboot launched, but it's been pretty encouraging to see some of the subscribers from the old version start reading the new one (also gained new subscribers I haven't seen before). The old version is still getting views, so I'm glad I decided not to take it down (or use the approach where I keep the same series but slowly overwrite the old episodes with new ones). Maybe in one year's time, I can do a side-by-side comparison of how both versions of the comic performed during their first year.
