seconding font suggestions - id also think about the voice youre writing it. its very disconnected, and you seem to be telling us what the images should be, causing them to be underwhelming. youve attached the voice to a character, so make it personal.
i think your art style looks really good, especially your lines, but sometimes you need a more dynamic angle, or pose, or up the contrast - currently, your story is falling flat because the art stays in a fairly safe space. its an action scene, so play around, zoom right in, then right out, make everything tilted, all sorts of stuff - at this point, worry less about it working and more about experimenting and enjoying showing your story in exciting ways.
