Great work on the cover, but the text makes everything so unbalanced.
The streak across the picture is the same color as the logo and makes it hard to read.
The text on the right could be placed comfortably in the empty space above it instead of crammed into a crevice.
The contradicting list on the top left is so long that it feels confusing instead of clever- and it cuts into your subject. You could get away with "Demon. Angel. Heartbreaker." "Don't worry, she's your guardian star."
I can't tell if this is a parody or you're making a Mary Sue comic. Regardless, the drawing itself is neat and you can never go wrong with those pink and blues. Good luck!
