Moejoe, I like this latest version of the musical notation motif.
Couple of things: for some reason the word "The" above "Song of Insects" strikes me as off (Maybe the type of font used? A need to be centered?) and the design below the center graphic should be directly below the the overlap of the clefs.
What is genre of the book? The color of the cover leads me to believe that the story is something stark. The title makes me want to know what is beyond the cover.....
