While going through the twitter account for the HeroTaru anime, I saw a lot of key animators/storyboard artists/other staff members for the anime posting celebratory sketches (such as these two). Are they fair grounds to upload here, or would they just be considered fanart?
Also, Ruia Shimakage has drawn a lot of sketches unrelated to the light novels/HeroTaru manga (like this one), so I wanted to know if it's okay to add them to the wiki too.
