I actively dislike cairnmea, for the same reasons I'm sure you're used to hearing, so please understand this isn't me dicksucking when I say the pages you posted are professional level quality. Even SFW doujins sell, especially if you stick to that niche. That niche being the shoujofags into skeevy dilfs that comprise a relatively small but also wholeheartedly invested/obsessive fanbase.
Just looked at your Twitter, have you done any comics before? I think your usual mode of coloring holds you back, but your toned shading here is strikingly good. Page composition also looks good so far, however that's more subjective and only have a sample size of one to work with. If you're just looking to improve, a little bit of dedicated coloring practice could probably take you pretty far, I can't think of anything else to rip into since the anatomy of what you just posted seems significantly better than on anything I've seen you post before. Unfortunately as you mentioned it's a weird time to be trying to work your way into a niche with Tumblr collapsing, but if you can find and stomach
a Twitter circlejerk, I think you'll start gathering a following pretty quickly. That's really the only way artists actually get attention, unless they're insanely good or barely-if-even mediocre at some kind of fetish art.
