I don't think I can show the "scariest" or goriest picture I've drawn here. I donno the forum rules, but I will say I ran a blog many moons ago (like 10 years) under a different name that was entirely gore, and folks pay good money for some depraved crap. I still like to think I'm pretty good at drawing blood and viscera but do so a lot less now a days hah;;
It's not everyone's cup of tea. Due to said blog, and how "big" it got, I got many messages insulting me and declaring me a psychopath and whatnot. Granted, I didn't just draw horror so that may be why. It'll happen, that's just the nature of the subject matter. Best to just ignore and make for whatever target audience you do have and want to foster. Forcing content onto someone who just... doesn't like it won't do you much good. That said, and as I said, there is an audience for such out there.
I suggest if your partner is uncomfortable with the subject matter you find a different editor-- not just for their comfort, which is paramount, but having someone who is better versed with the stuff will be able to help out more and be more willing to pay attention rather than just get it "over and done with" so they don't have to engage with things they don't like.
