#14,#17,#18: We like the core idea of the icon, obviously :). We suggest some changes in the book in order to not confuse it with a flying bird. We have preference to icons placed horizontally at the left of the name, for this reasons we find the book/icon proportions too landscaped, could you square it a bit?
#18: We like very much the bright colors, but may be it will bee too expensive to print in CMYK. Could you try to use a single color for the globes? By the way, the globes suggest a book about many people chatting, could you use squares or bubbles?
#14: We like the squares, may be they are a bit too small.
