Is your protagonist a guy or a girl, because the first picture hints that it's a girl, where as the second hints it's a boy. I like the first better, though Revolutionary needs to be a brighter pink, it's kind of fading into the back ground. Also a book cover is long vertically rather then horizontally, you need to reword it for that orientation.
As I said, first one really grabs me Where did you get the photo from?
Protagonist is female, but the antagonist is male--but they're both extremely important, so I wouldn't care who I put on the cover. And, yes, haha, I am aware that book covers are vertical. It's just a banner for the site when I post it. I found both the images on Pinterest. Thanks for the feedback!
