The anime definatly lacks the style that the manga has. Some scenes just annoy me and look so emotionless. Though I have to admit the fight scenes have decent animation and frames. The latest episode (11) was by far the best in my opinion on terms of artwork.
I read the translations of the novel a long time ago, when they first came out, so I don't remember much about them. Gotta reread them sometime soon. I miss Timcanpi's updates. 07Ghost was another great series they had.
