The art looks really promising, and the action scenes are super engaging.
I suggest you to mark the first episode as 'mature' though, since there's blood and slight gore in it. And I think you can omit the basic story section, since it's already written in the synopsis section.
I also agree with @kimketli regarding placement of the speech bubbles. Since you finish up the pages digitally, you can draw the pages as usual, then just space the panels up so that there's more room to fit in the bubbles. I would absolutely discourage reducing the size of the text, since it's pretty small to begin with.
