For all of the bellyaching I do about my art not being good enough, I realized that when I'm really invested in a comic I might not pay as much attention to the art. Of course I'll stop to look and admire it if it's really good, and maybe I'll look for little background details, but if I'm really speeding through the story to see what happens next I might not spend that much time there.
One really cool thing I heard is that artists can be valued on two things: their wrists and their brains. For instance, one artist might be called in to do really detained spaceships, while another will be called in to do a number of character concepts. One was was called in for their detailed draftsmanship and their other was called in for their problem solving skills and innovation. Obviously you need brains and "brawn" to do something like comics, but I do feel like some artists excel more in certain areas. I've noticed that the attraction of really pretty art will eventually wear off after enough time and the only thing you'll be left with is the story. I've read through dozens of pages of really sketchy art that managed to hook me with it's dialogue and character interactions, but have given up on comics with great art and a story that went nowhere.
When I think of "bad art" in comics, I'll think that if the story is good enough the only "bad art" that could turn me away is the kind where I genuinely can't tell what's going on. I'll sometimes get annoyed at mediocre art ("You call that perspective I drew better than that when I was in middle school!"), but I'll know that's because I've trained myself to see things like this. The average viewer might not even notice it.
So, what about you? How bad does the art have to be to stop you from enjoying the comic? How do yout hink about these things when you're making youre own comic?
P.S. This is where I heard about that wrist vs brain thing.
