Man it’s really bugging me that I can’t seem to track down a source for that amazing set of ‘before’ and after special infected fanart that’s been going around. When I tried a reverse image search hardly anything came up and what did was Russian and on forum-like sites that i still don’t think was the original artist posting them. I used a translate application and saw a comment that seemed promising

reference to the original do not forget: 3 http://fk-2014.diary.ru/p199048825.htm
but the links require a login to view so I still can’t look to confirm for sure that it’s the original artist :/
