Writing matters the most. Artists with varying styles can catch my attention if they write well, even bad art can keep me around if the writing is good. It’s why people like sprite comics, or those stick figure joke comics, or old bethesda games. The art only has to be tolerable. Pretty art is just icing!
I have had plenty of beautiful comics on here that...had very choppy or exposition heavy writing. The bad dialogue, feeling like I am being told what to think of the story, ect drew me away from it. You gotta know how to show your reader the story, even if your art is iffy.
Now, the problem lies in if the artist is capable of telling the story with their art skill level. Or if the artist/writer has the maturity to write something cohesive and show, not tell, a story that is worth it. Seen a lot of that too! Where the concept is phenomenal but the writer is clearly not ready to write it.
