Ngl I'm personally very biased to korean manhwa or manga style art but that's probably because I like a certain type of genre (which is romance, fantasy or on some occasions, action). It's a strange thing to say but when I see a certain art style, I can already tell what kind of story the artist wants to tell. And if I like that type of story, I'll sub to it. I'd say that unpolished art doesn't bother me though (as long as it's still manga/manhwa style art) unless it's traced. Again, the specific genre is more important to me than anything else for me to click on it XD
What I do want to say is that regardless of the art style, you will attract an audience who likes your content. So don't worry too much about it ^^
