Art style isn't that important to me. I read comics that have westerns style cartoon art, more realistic style art, anime style art, simplified styles, digital and traditional. I will read anything as long as the story is interesting to me, and I'm invested in a character. I don't care how beautiful or polished your art style is, if the story is uninteresting to me, I'm not going to continue reading it. I'm all about that plot, and as long as the plot is good and your art conveys the emotions and movement of that plot, I'm on board!
I don't actually start reading a webcomic until I read the summary. If I don't like the summary I won't read it, even if I found the cover art interesting.
