You ever watch that movie 'Field of Dreams'?
I haven't, but it's literally not possible to have grown up in the 90s without having heard its incredibly famous quote:
"If you build it, they will come."
It's not nearly as simple and straight forward as all that, but in general, there's an audience out there for you, for whatever niche genre you want to write in. My own comic is a fucking Power Rangers series for Christ's sake, it doesn't get much more niche than Tokusatsu, even in Japan where the subgenre originated.
The audience IS out there. Sometimes the audience is hard to find, sometimes they're small and spread out, and sometimes they don't even know they're a part of your audience yet, but they ARE out there.
Of course, You can't just build it and expect people to show up out of the blue or anything:
But you can pour your heart and soul into making something worth coming to see.
The best piece of advice I've ever received with regards to perseverance is that you have to be your own first fan. You have to believe that what you're making is cool and interesting and worth checking out, because if you don't believe that, then how the hell do you expect to convince anyone else of it? You have to be a genuine fan of your own work, you have to be actively excited to share it with everyone, to win them over through sheer enthusiasm if nothing else will work. Believe that what you're making is worth sharing enough to share it everywhere, and you won't ever be discouraged enough to give up on it.
I'm not sure if that's necessarily relevant to your precise issue here, but it's something that I consider extremely important and worth sharing regardless.
I just went and looked at your work, and it DOES seem as though you're a little scattershot with your approach. This isn't necessarily a bad thing, but it makes me think that perhaps the above advice might be more relevant. It also might not, so take this with a grain of salt, but I have to ask, looking at so many short series that jump to a ton of different topics, is there one that you're genuinely more passionate about than the others? A single, continuous storyline or central concept that really grabs you and won't let you stop thinking about it?
I'm not here to tell you what you should or shouldn't prioritize in your own work, nor am I going to try to tell you that you don't care about what you're doing, it's just that in my experience, those types of stories and concepts are the ones that actually gain some traction.
All that being said: Big audience =/= good audience.
I've been doing this for a while, so I know how difficult it can be to divorce your mind from the numbers game: having a big following on Twitter/Instagram or a bunch of subscribers on Tapas and Webtoon and etc. etc. definitely gives your brain The Good Chemicals, and that's worth something in and of itself, but it's not the end-all-be-all of your career as an artist.
To be perfectly frank, as hard as it would be to admit, I would take 100 fans who genuinely love what I do with the same kind of passion and excitement that I have over 100,000 fans who are just mildly tepid about my art.
(Edit) Actually, come to think of it, I actually DID have something like this happen to me. My primary source of income is as an adult illustrator, and back in 2012 or so, I was mostly on Tumblr. In 2017, Tumblr decided they didn't want ANY NSFW content on their site at all, and I was basically booted off of my home base wholesale. I transitioned over to twitter, and I literally lost 90% of my audience. I went from 15,000 followers on Tumblr down to 1500 by the time I made the full transition to Twitter, and you know what? Basically nothing changed. I still got likes and engagements on my posts, I still got commissions and patrons, and my discord server was as active as ever. That 10% of my audience who stuck around were the real driving thrust behind my ability to support myself doing my art to begin with, so losing over thirteen thousand followers didn't actually do much to impact me.
Being 'the big popular' sounds really nice in theory, and it probably would come with some upsides, but it's meaningless if the following and interactions you get are shallow and lukewarm. Like I said, the audience is out there, for every story, it's just a matter of finding it. Sometimes that audience will be small, but oftentimes those smaller audiences are the ones who most fiercely love and support their creators: They know there aren't many of them, so they know how loud they have to make their voices in order to encourage more of the content they want.
Once you find an audience like that, and it is just a matter of time until you do so, then treasure them as closely as any friend or family, because fans like that are hard to come by.
Apologies if this is more esoteric than what you were looking for. As far as practical stuff, I think everyone else here has you covered: Post consistently, get on all the socials, art trades, fan art, etc. etc., but when I see discussions like this, my mind usually wanders in the direction of the mindset and the all-but-unavoidable defeatism that can come with it, so I try to combat that with different ways to think about what you're creating and why you're creating it. I hope it was able to be of some use.
