Quote from Xiin
Art by Ai Yazawa (Nana, Paradise Kiss), and Tsutomu Takahashi (Blue Heaven, Jiraishin).
I second to this.
I also love the art of Honey and Clover (I forgot the artist). It lifts me from the "anime" environment to a more realistic side.
I hate new new releases of anime nowadays...they just have the same art. An example would be Vampire Knight. Thouh I love the story, the art style was almost the same as with Melancholy of Suzumiya Haruhi, Shakugan no shana, Ouran and so on. The palettes used were...err...too bright...too anime.
