Art: I think the art was outstanding. Everything was in full detail, from the serious battles to the small cute immature conversations. It really caught my eye, hope it catches yours.
Character: At some points in the story, the characters behaviors made no sense and sometimes just plain annoyed me, but over all, I think they had good personalities. There were different people, who almost all of which (even the most serious ones), made me laugh alittle, but they could be serious.
I honestly loved this anime, though I wouldn't rank it my favorite. It had action, good quality, romance, and some incredibly depressing momments. It has almost all the things I'd find in a good anime, but it wasn't exactly so great that I'd name it my top, TOP favorite. But it was still spectacular, so I would suggest you watch it.
