Wonderful way to get into the Book of Mormon.
I have a few suggestions that would bring it to 5 stars. (1) Give scriptures references. For example, the text for the Liahona could reference 1 Nephi 16:10 in small type at the bottom. (2) Add more of the important parts. I'm thinking of Lehi's dream, Alma's teachings on faith and planting a seed, maybe another page on the wars (e.g. "When the Nephites obeyed God, He blessed them."). Of course, it's already almost an inch thick.
I have very minor quibbles with some the illustrations. For example, it show Laman and Lemuel not helping build the boat when they eventually did. ("He built a sturdy ship ...", not "Nephi and his brothers built ...") "... if the Lamanites learned about Jesus, they would stop fighting ..." would perhaps better be "... if the Lamanites followed Jesus, ..." When Jesus is born, it shows people looking at a star at night. The Book of Mormon is explicit that it was as bright as day. The Shining Stones (Jaredites) shows the boats FIRST on the sea, THEN God touching the stones. It may have been clearer to put the touching first, then the boats second (but how do you show the stones glowing *inside* the boats??)
