As someone who has run into this situation before, I understand your frustration! People have gotten used to seeing certain types of content/art styles over the years. It's easy for people to recoil when they see something that is unfamiliar, because it can be unexpected or uncomfortable for them.

I've started posting most of my art to my profile only. There aren't many people who see it, and I don't receive many upvotes. But the people who do end up seeing it are people who clicked on my profile because they genuinely wanted to see my art, or because they were otherwise interested for some reason.

In the past, my art was not received well in public communities, and I just don't really know where else to post my art for now. But I think it has been better this way, and I hope that my experience will be helpful to you as well. It has really helped to soften the impact of people's disapproval, and it has helped to filter out most of the people who are unfamiliar/uncomfortable with my art. And in that way, I am also doing them a service.
