Wow, based on what I saw on Webtoons, you're doing pretty well over there.
And I have the feeling that Fantasy/Action genre might give you a boost. Fantasy tends to be popular over here, or that's my guess. (I'm a beginner, well kinda, been here ten months...)
But I'd still keep in mind what the previous have said. You gotta make a great first impression, which I think you'll be okay on. Still, you may get a lot of views, but the sub count could grow slow...unless they come over from Webtoons...
Honest, just keep your uploads consistent, whatever time/day you pick, as Heady says, and be patient with the "numbers" as Thunder Chicken said. (I upload Saturdays) Announce in the forums when you start publishing, but don't spam the Promotion threads. You'll get numbers, sure, but not often diligent readers, if that's what you prefer.
I will occasionally go on them if there's some fun to be had (like promote your story with emojis or something silly) And it's good to leave panels/snippets of episodes instead of some "static" link.
But despite it all, growth can still be slow no matter how much you promote, and don't beat yourself up if it is.
...
Unless maybe you'll go viral after the first few eps and I'm just talking nonsense, lol!
I'll keep you on my radar, mate.
Good luck!
Edit: As far as length of episodes, keep them short. I've learned that people tend to read while commuting, or if they binge-read, then it's not as cumbersome to catch up. Just a thought (from a fellow binge-reader.)
