Ehh, seems like he's using traced or just straight up copypasted art from others. I can recognize a couple of characters there like Android 18, Illya and Asuna
A parody of anime, manga, visual novels / video games or other characters is not "stolen" art, and it don't think you understand what traced means.When you stole art from doujins and turns it into a game lmao.
Doujinshi refers to self published manga/comic btw, none of the art came from someone else's work.
