Harada, Rihito Takarai, Hidaka Shoko
My favorite is Naono Bohra. http://www.mangago.me/home/photo/352832/ and. http://www.mangago.me/home/photo/353551/ are just 2 that I like. I have a whole album.
All the authors mentioned above, togura tohru, gusari, abe mayuki, yamamoto kotetsuko, natsume isaku, kanda neko, ugh and etc. too tired to type more than this! haha... all of them are yaoi manga author, but I have too many favorites for other genre too haha (づ ̄ ³ ̄)づ
Maruya Kae
I'm really surprised no one has mentioned Yamane Ayano. Her work is precise, clean, elegant and finished but also very expressive. And I'll add another vote for Scarlet Beriko, also Zakk's style is adorable. Love Zaria's rococo opulence.
But for sheer artistic gorgeousness, it has to be Toqa Q of Guilt Pleasure. A virtuoso.
Which manga/artist has the prettiest art style in your opinion?
