I don't know about whether the art became awful or not, but I must say the new art style isn't as appealing to me any more. Before the changes, I must admit the style was weird, but the style matches the bizarre story itself. So I like the previous art style. Now that the style has changed I think the feel of the story has changed. The characters I think look more mainstream now and so I think the story actually loses some of the strangeness of its plot setting. I barely recognize some of the characters anymore.
What happened to the art. It went from decent to awful. The original (beginning) art was not the best but it was good in it's own way. Now it totally sucks and lost all it's uniqueness. It's like they're not even trying. Except for the characters, most of the pages are blank. They don't even bother with the background. It sucks since this is an interesting story and the change of art kind of ruins it. I don't know if I'll continue reading it...
