Not directly to OP, but tbh if, you're not drawing webtoons professionally, just do what you can, the best you can. I read TONS of interesting Canvas titles which less than 15 panel chapters and they have a lot of subs and patrons. Usually they balance the small amount of panels with faster paced writing and meaningful action. If someone complains, tell them to gobble on your chinchin.
If you want to be a pro, tho, unfortunatelly there is not much escape. Once users get used to a certain standard, it's too late. If they are paying, too, it's Oof. I'm getting back from a year and something hiatus because I couldn't even stare at my own characters anymore, and I'm already spreading some oil on my back to make the lashing less hurtful. Professional Webcomics may be an excruciating journey, but hey! It's also where I get my best pay and it's my most successful artistic endeavour so far...
Another thing, "Golden Age" on Webtoons is long gone. If you didn't make it to Originals until 2019, it will be reaaaaaaaaaaally hard for you to get an audience now. Most probably WT will kep squeezing Lore Olympus for more 10 years than investing in new IP.
