Well, I'm a creator too, so I know how it feels when you post something (on which you worked for hours on end) and it looks like as if no one gives a damn lol.
Anyway, I took a look. I won't comment on your art, not because it's bad, but because you'll improve with each page as long as you keep drawing your comic. So yeah, art wise, keep drawing, you'll definitely improve and the overall look of your pages will start getting refined too. So yeah, keep those artistic hands moving! 
Coming to the main point: readability. This is very important. Now in your prologue, the part where 'soul shards' is written, the text there seems to be blending in with the background. I understand that since the text is in white, so even if you 'bold' it, it will still kinda merge with the bright background. What you can do to rectify that is make the text black, but put a white outline (thickness of the outline depends on your preference) to the text...that will make it perfectly readable.
Another, last thing you can do is decrease the size of your font, at some instances it was breaking past your balloon borders.
I can't yet comment on the story yet, because of the obvious reason of not much pages being there. I've subscribed though, so I want to see how you improve in the upcoming pages.
Btw, you do work on layers right? Cuz if you do, I don't see why you can't just delete the colors going past panel borders in a matter of seconds.
