on 73, we really like the design. Can you make the book one color? (i.e. black, or green, or any color), and then make the people inside either one or two colors? If you look at the design we have placed second, maybe even play around with the color scheme they used? We really like the color scheme there.
Essentially we think the logo you've made is great. We do want to try some tweaks (for example, right now the book is curved, we want to try and see if we could have a hardcover book, essentially have the backs of the book be flat), but we think the design is great and want to start tweaking it. Well done so far.
