Re: What category would videogame/comic book fanart be under?
If it is COMIC style, I would recommend Cartoons.
Both manga categories should be used for Manga style art only.
Superman, spiderman, video game characters etc. fan art is not considered a type of Manga.
The best way to support our community is to just keep drawing - even if it's for fun and not serious. Another way is by taking time to occasionally rate and comments drawings by new or learning artists.
