Interesting, it makes ask yourself. Is it a heart, love for the book? Or is it the book you love and you read it because it's winter and you can't go out? LOL
While it's rarely a good idea (composition wise) to center a subject, this is one that is acceptable.
If the heart shape is meant to be prominent, then it would be better, and have more impact with much of the right side of the book cropped.
As it is, the book and the heart shape get equivalent attention
