As long as you tag it correctly and keep any images or heavy descriptions under a read more, body horror is fine regardless of fandom. Anyone who says otherwise are 1) trollers, 2) people who try to "cleanse" fandom spaces, or 3) people who believed they could handle it, couldn't, and take it out on the poster. Unfortunately, unless you're in a fandom of a media known to contain body horror, you will get a lot of those people.
But keep on posting what you want. If people don't like it, then they don't have to interact with it. It's their fault if they continue to do so.
Besides that, I also wanted to say I like the body horror you did of Ingo. I am well aware that I have a messed up sense of what constitutes as body horror so when I first saw the pictures the first thing I thought was how inefficient and annoying it would be to constantly having to carry your own organs. Like, the hands at the bottom front would be the best ones for picking up stuff from the ground in front of you but nooo, they have to be used to carry organs. The body horror was still good though.
I do apologize if this came off as haunty or unnerving, I am not the best at communicating my thoughts clearly or fluidly.
thank you-- I'm a big fan of body horror, coming from the little nightmares fandom! I've been fixated on submas as of late as well as look outside, but submas is not a horror fandom- although there have been horror aus i've seen (and enjoyed!) So i wanted to give folks ample warning- cuz i understand not everyone is as interested in that as I am- also you're spot on- He likely will later get a shirt or something for the organs but sadly the lower arms still won't be too useful- they're incredibly clumsy and he has to really focus to use them!
