Yooo we have the same vibes haha I've been plotbuilding/worldbuilding/characterbuilding for like 6 years so far.. I've still got lots to do before I'm ready to publish my comic and print it but I've got goalposts planned for the next 10+ years Including making and selling hardcopies and merch tho that is still putting the cart wayyy before the horse haha.
My project, H@くK, is a Fantasy/Solar-Post-Cyberpunk/Sci-Fi story that spans across roughly 24 story arcs with 2 worlds, 5 main characters, and 100's of side characters, all of which will be meticulously built out.
It is a story that I will turn into a webcomic, once I have the plot fully built out.
There are many things I am doing/planning to do (all on my own) that will all result in the eventual release of my webcomic:
Plotbuilding - I've written about 500k words in my plotbuilding doc, but I've got lots more to develop
6 Fully Animated Trailers - storyboarding, animating, making the
music, making the voice acting with Synthezier V, compiling the trailer, and adding sound effects
Maybe some 3D modeling for environments
2D asset creation
Working on my website (That i coded all on my own - super proud of that as its the first website i've ever coded and it turned out exactly how i wanted it to be!) https://mitsukiyouko555.github.io/hackwebcomic/
Making the artbook for worldbuilding so that I can sell it with the comic volumes eventually creating the backlog for the comics so when I post it online once every week or two
Make and sell merch such as stickers, pins, prints, shirts, stands, etc. (Maybe even 3D figurines of some characters)
Once I publish the comic online, I plan to print physical copies to be sold and bundled with my artbook, and/or other future volumes.
All that combined may take up to 10 years before I can post my comic online... which is why it is still an ongoing project.

I also post my art on IG: https://instagram.com/mitsuki_youko/
and my music and animations on youtube: https://www.youtube.com/channel/UC2_j3oXTtc4KbePI4jvSdyA
Sorry for the long post lol but i couldnt help but share my project since you also seem to be doing something similar! 
. I have tried webtoon format as well but I want to have a physical copy of my comic in my hand one day
Same thats why when i post on webtoon (when the comic is ready) it'll be the reguler comic style rather than webtoon style.. I find that if you split ur page into rough 3rds you'll still be able to read it decently well on the phone as well even tho its not webtoon format.
Much like what Par0lell does here: https://www.instagram.com/p/CdDvtfFvdqH/?img_index=1
