very good!
Not a bad tutorial, it was really great all in all. The thing I found a bit annoying was the page turning, it went all to fast. Another thing is the music. I don't know if I'm the only one who thinks this but the music got a little annoying after a while, maybe you could've added more options to the music selection. Those things are the only things I found, that I wasn't too pleased about. But all in all, those things can't ruin the fact that you made a great tutorial, really informative. Good job!
