it's an original art style of the artist or studio. Unless they change the person, the artwork won't change anytime soon.
What's wrong with the artstyle?
For me, it's okay since the story outweighs the artstyle but it's preferable if the art is the same as those mainstream webtoons. It would probably much more popular if the artstyle is comparable to solo leveling , ORV or other action kr webtoon.
Ahh...but the artstyle being diffirent is actually the charm, artstyle shouldn't be a basis of the story whether it should be popular as oppose to the other known ones...OPM originally is popular even though it was drawn doodle like back in the day...

But kudos for sticking in the webtoon...
For me, I usually judge whether to continue from the prologue or not based on the art style. Let's say there's an ugly webtoon with a good story in the latter part but if that webtoon can't get my interest in the first ch. I wouldn't continue to read it. Some good stories remain underrated due to art style that's unbearable. To me an example that has a high rating but something I can't stand to read is "superhuman Era". Honestly, I rather look at a handsome MC. It's disappointing that the artstyle of the cover of the novel and the actual webtoon is different. Good art can also be for simping characters.
Ahh I see.
If possible, in my opinion, they should change the art even just a little.(づ￣ ³￣)づ
