I have a good idea for a マンガ and even have some of the chapters already drawn and inked! So, where can i get this reviewed and published?

idk

(google) publishers of アニメ I'm sure its not to hard to find または seach some thing in that general idea maybe あなた can get some numbers

if あなた want to get other アニメ artists to review it go to deviant art and get a page. post あなた work there and enter their clubs, they have a lot of アニメ クラブ and there are a lot of professional artists who post there. あなた can also see my art there link so there is the link, enjoy and good luck!
