Sure. I casually read webtoons in my freetime and am a huge nerd for storytelling so I don't mind.
If we're talking purely art style and presentation, I think that there's no real "right" way to do it. Most of the popular examples I listed are all over the place. Compare Lore Olympus to something like Cursed Princess Club. Wildly different. None of the art in the comics above I'd say is particularly GOOD by /ic/ standards, but it's not horrible to look at.
I think viewers tend to like heavily stylized, bright, beautiful colors more than dark and moody, but as long as you make it work with the story you can succeed (Wrath and Dawn is pretty moody, but it's also very Arabian)
I think it's more heavily dependent on the flow of your comic. If you read some of these, you don't really get tired or bored, which is a really handy skill.
Being able to balance visual and written stimulation is hard, but in general make sure all your art is leading your viewer's eyes somewhere. Have characters look towards or point to the next panel. See pic related.
Don't overwhelm your reader with a wall of text, or too much information. Allow them to learn and explore through showing them, giving them hints, allowing them to make assumptions (right or wrong) because that's what keeps them coming back.
