I read the first episode and here our my thoughts. First the good: You have a nice art style. The characters look distinct from one another (for the couple you have shown). Now the bad: It's a slide show not a comic. You have lots of tell and almost no show. Comics are a visual medium. It seems more like a picture book. Reading it also had a lot of scrolling for very little payoff in story. I really have no idea what the story is. I don't mind keeping the story vague, but you have to give me a reason to read the next episode, which this didn't.
Conclusion: The art is above average for a webtoon, but the story and structure needs some work to be readable.
