I think the concept is quite cool and I like the general idea for the cover!
I do think there are some things that could make it even better though. For the text, I would move it down a little and also experiment with possibly putting the word "story" next to "human".
I think some compositional elements could also be changed to make the cover stronger. The main elements of focus seem to be the girl and also the blue orb in the middle. Moving the girl and orb a little would help with bringing greater attention to those elements. I would move the girl a little more to the right as to work with the rule of thirds (if you don't know what that is, it's a compositional grid/system that helps to highlight focal points, here's a nice link that kind of explains it ^^), closer to where the left line of the window frame is. For the orb, I would experiment with multiple positions, I can't really think of the best position for it at this point.
One last thing that might help is making the girl's line of sight match with the orb (although if you don't want her looking at that then never mind) Right now she looks likes she's looking straight on and making her body shift a bit more to a 3/4 view might help.
Hope that helped a little and best of luck with your cover and comic ^^
