Studio Khara, which holds the rights to the Evangelion franchise, has now released some guidelines for fan artists who seek to draw illustrations inspired by Evangelion.
It looks like fan artists are getting a few restrictions if ever they want to draw Evangelion fanart.
As for selling fanart, Khara is still evaluating even more guidelines for that.
Currently, they are asking the public to comment on the matter, and asked everyone to wait a bit further for these additional guidelines.
