Personally, my two cents on the matter OP mentioned is that you have to realize that there are going to be things people like and don't like. You may have the juiciest peach, but there will be people out there who don't like peaches. Plain and simple. Sure it sucks that you spent so much time growing the peach, and there will be people that admire it and think it's pretty, but when it comes down to it, you can't make people eat the peach.
I think what matters most is finding people who genuinely enjoy your content for what it's worth and really appreciating them. Ask your followers to promo your comic for you if you're able to. Some comics take a while to really gain traction, some don't. That's just how it is. But there are people out there who will enjoy what you create. You may just have to alter how you view that success.
Realistically, I currently only have 7 subscribers, but I'd rather have people follow me who I know will enjoy my story and who are there because they genuinely do care about the plot, characters, and everything else that comes with it. If you measure success by the amount of subscribers you get, you're always going to find some way to be displeased by the results you find, no matter how much work you do to market yourself.
This isn't discrediting the fact that most creators do put in their fair share and that there's things that Tapas could probably do a bit better. But ultimately, what will affect your comic the most is doing it because you enjoy it.
