This is another cool idea, having an image in the back and a white square in the front, I like the cropped corner, gives it some flair.) Could do a lot with this depending on what you settle as the title of the book.
Love the white tree and column of text, really pops with the deep colors of the image. Headline fits the mood of the image. Could incorporate the white cut outs at the bottom of the page on a double page spread
