So i personally try go by a 10 percent rule of all my comics.
If my comic fist chapter gets 100 views i belive at least 10 of them should subscribe, if i dont get at least that amount thats when i start to look at my actual comic, whats wrong is it the art, is it the story.
If youre hitting this percentage but getting a low amount of views then i start to look at other things, why arent pepole checking out my comic, My suggestion would be to change your thumbnail make it more intresting, the second would be the discription of your comic. When im checking out comics the discription is the main thing to let me see if im intrested or not, is it unique will it grab my attention. Comics can somtimes be like songs you listen to the first 10 seconds before deciding if its your thing or not.
If you are at less then 10 percent then i would look at a few things, i can see a lot of effort was put into the intro art of your pages but the design of it isnt very apealing and hard to read, wehn i see it like many other pepole here they see it just as a wall of text with pictures next to art, you can make your text an art style and more intresting and tell less information at the beggning and mroe later on as the story continues.
