Well, if 你 talk about how well the 日本动漫 was drawn in relation to the story, i would suggest "five centimeters per second." it has great art and a good sad plot that leaves 你 both happy and sad at the end.......
and i also like "Garden Of Words," "K","Clannad" and "Clannad-After Story." All of them 显示 great art style in the drawing tagged along with a good. It really brings out the beauty of the story.
(note: the image is a screen shot from five centimeters per second)
5 Centimeters Per Second~ *pic The most beautiful art style I've ever seen. I didn't like the story line that much but I just couldn't take my eyes off of that whole movie the style of it was just beautiful~
I also like 天使 Beats art style! And lots of people bash Hetalia's first 4 seasons art style but, I thought it was really unique. It might not work for most other animes but 黑塔利亚 is just a light hearted funny crazy 随意 显示 and for such a 显示 that art style was perfect. Any other would be too serious for it~
For best art I'd definitely say Sword Art Online 或者 Zetsuen no Tempest (spelling?). I also like Kuroshijitsu, Durarara!, and Death Note. Code Geass has amazing animations but the faces are kind of screwed up...
Hetalia. Despite the fact that they change the art styles, I still think both are amazing and fit the comedic anime. Here's a pic comparing the two styles for the character England/Britain(depending on the dub) The lower one is the older style.
