While reading it, I don't mind this approach personally. But as the OP asks why you're not gaining popularity - you need to keep in mind you're posting as a comic, not a novel. While yes, you can do this paragraph format and it can fit what style you enjoy, the fact is your first episode is what hooks new readers and gets them to keep reading. They're opening your comic expecting a comic - but that first while of scrolling is blocky paragraphs.
If you want to keep this approach however, I recommend trying to trim it down a bit. There's also an over use of the word "galaxy/galaxies" that make it kind of stiff to read. The program Prowritingaid has a free trail that lets you test smaller word counts and might be helpful for analyzing these paragraphs for repetition and readability.
With the comparison that your format in the beginning is more Telling than Showing the reader this is another example:
this part could have had the owner saying these things in speech bubble, to make it more like reading a comic than a picture book. However, personally I think it works since it gives a news coverage feel to the beginning of the story. But I'm also on the fence, cause I know the standard rule to catch readers is to "Show Don't Tell."
I realise this style is probably intentional, but as you're asking why it's not popular - to be blunt these might be reasons why. This style of narrative isn't bad, it's just not as preferred by the general audience. So if you're worried about gaining popularity, these are things to consider.
From the OP to checking it out now, it seems you've changed the thumbnail and blurb. I think you've made good improvements to both of these
