He is always know how to creat emotional touch within his animation. And he is a real master at background drawing and painting.
If you are interested, try watching “Hoshi no Koe”, “Kanojo to Kanojo no Neko”, “Kumo no Mukou, Yakusoku no Basho”, “Byousoku 5 Centimeter”. Whether you interested in Japanese animation or not, the art in these animations are still stunning, especially the backgrounds, they are really worth watching.
