If I had to guess what she may have meant with the details she liked in the second one, it's probably the angel statues, one of which you could add as a framing element on the back cover as JonHop suggested. Either that or the stars, which are also easily added. The composition is indeed better on the first, and if she already likes the mood on that one, I wouldn't stray too far from it if I were you - it is a very nice image, maybe you've just been staring at it for too long?
