Somewhere in chapter four it all changed. Same artist, same style, but wow, 100% improvement in the art. (Enough so that now and then I stopped reading just to admire a page's art or layout.)
If you do check it out, don't give up if the prologue doesn't work for you. It's kind of odd that they included it, since the nature of it really doesn't reflect the rest of the story.
Four more chapters left to read! Yay! Metanoia isn't as good as Vampirates, but it's still a darned entertaining story. :D
