If you wanna read manga you should try Mushishi if you haven't already. The anime is good too. It also has a live action movie. The best is the anime apparently, because the story is full of colours (so manga would have trouble to create the ambiance, like when a guy is amazed by a rainbow-like swam of mushi a bunch of black dots are not going to convey the beauty well), and the movie got a bad writer or something. But the manga is good too, I like the storytelling and how the artist did the strokes of pen.

And Tatami Galaxy/Youjou-han shinwa takei is a must watch if you want art quality anime.
