Well, Soul Eater's art has really improved leaps and bounds... I think I've said it before but I really love the style of Katekyo Hitman Reborn. Franken Fran is loveable though. There are many more that have great art both for characters and their setting that I just can't think of right now. >>11766269

And it goes without saying that anything by Oh! Great will look great.
