Final Textbook project - looking for feedback

my final layouts for the textbook project... even though these are final and will be printed, feedback would be appreciated!

I would like to add that this was not the easiest project for me but i think my content came a long way. I was really slow on editing the opening page throughout the process simply because I had a hard time getting into this one. After I messed around and completed adding the information, I was starting to like my designs more. I feel i struggled with pulling everything together to fit my theme. But I ended up enjoying my iphone layouts most. The second text book spread was my main concern and I think I would like some advice on how it turned out.
