This is going to be the meanest answer, but for the sake of learning, not necessarily what I'd actually do, I'm going to give this hypothetical answer: "I stopped reading at the info page." because this does seem to be struggling to get subs in spite of decent drawing, and I ran into multiple things that could put somebody off there.
So...
The title gets us off to an inauspicious start: Archport City Chronicles Lockdown. So...I'm sat thinking "is this part of a series?" Archport City Chronicles implies this is part of a series, and then Lockdown doesn't really suggest it's the first of a series (because I'd expect to get to know what a city is like in more normal circumstances before I see it in Lockdown, and without context, I assume the city is on lockdown, not just the protagonist), so I'm already like "Oh...er... is this like... book 2 or something? Is there an "Archport City Chronicles: Origins" or something?
It doesn't help that on a personal level, as an experienced creator, I see a new fantasy writer calling their stuff "X Chronicles" or "The Y Saga" and immediately sigh because it's a really common beginner error to start talking about your story like it's part of a big series before you even know if anyone likes the story enough to be interested in the first book, never mind a sequel. It doesn't fill me with a lot of confidence I'm going to read a confident, polished product. Creators who call their work "chronicles" or "saga" have a tendency to have a ton of pointless side characters who are only there to advertise potential spinoffs, or to leave hanging plot threads for sequels that'll never be made, so I tend to treat works with titles like that with a lot of skepticism.
Then we get to the banner.... It's depicting a really complicated scenario that doesn't really make me feel any the wiser about what's interesting about this story, and it prominently features these signs where the typography is an important element, but they're written like somebody's handwriting in biro on a polite note and without enough padding between the text and edges, so you're immediately drawing attention to a piece of amateurish presentation. The banner is decently drawn, and I can see a lot of effort was put in, but the confusing scenario and the way it draws attention to the lack of effort put into the typography means that the first thing a reader sees sets up the expectation: "Amateur comic."
Then there's the blurb. The first thing the blurb tells me is that this comic is struggling to get readers, so that gives the impression, "people aren't buying this, it must not be good". If you present yourself as a loser, people will think you're a loser. No matter how badly your product is selling, you HAVE to sell it in a positive way. You have to make it sound like it's a fantastic little comic, get it while it's hot! You won't regret it! But also... do not EVER put unrelated stuff like this at the start of your blurb! ALWAYS put what the story is about FIRST!
Then it tells me that IF it gets 50 readers, it'll reboot!? As a better version of the comic? ...So, you're telling me... that you could make a better version of your comic... but you're only going to do it if I subscribe to the less good version of your comic? Can't you just...you know... make the better version of your comic and then I can read that better version instead?
If you're capable of doing a better job, you should just go and do a better job, and you certainly shouldn't tell the reader that you're currently not doing the best you can to entertain them. You're basically inviting me to your messy house, and then saying "if you promise to come over again and to bring friends, I'll tidy my house next time!"
Then the blurb actually describes what the story is about and it doesn't lay out any kind of exciting sounding stakes. It's about a world where everyone is nice and kind and a protagonist who doesn't want to be there and doesn't want to have adventures. Okay... does anything exciting happen? Or anything funny? Or is there some danger involved? You're making your story sound a lot more boring than it probably is.
Then we have the cover, which gives the vibe that it was a fairly nice piece of work that felt bare so you just kept adding stuff to it, like the multicoloured background that makes it hard to pick out the characters because of the similar value and saturation, and the very bold and complex frame around the edge. The title font is too small and fiddly, and so all together the impression is a decent drawing and then a bunch of stuff added in an attempt to make it look more finished, but without enough design knowledge, so instead of making it look better, it's made it look fiddly and overwrought. It may be time to look up resources and tutorials on cover design.
Final nitpicky thing: No unique thumbnails for episodes tends to first make me assume it's a novel, and second to assume the creator wasn't willing to put in those few extra minutes of effort on their presentation. So that's another bad first impression.
Hopefully this has been educational. Fortunately it's easier to fix these things than to fix all the rest of a whole comic. Read some books on the fundamentals of graphic design and typography and study good covers. Your drawing is good, but you need to start thinking about the finer points of how you present and talk about your work, and how to make the best first impression you can. If you're planning to make a new version, just start making it, and use it as an opportunity to rework these things I've brought up with a nice clean slate (a lot easier than trying to rework an existing comic).
Best of luck!
