Its very interesting and it gives you plenty of tips, naturally you don't get absolutely everything there is to know, as its not a text book, that's where the actual courses, teaching, and practice comes in. it was informative, beautiful, and interesting. A lot of the information is actually available on youtube, if you type in the authors name you can explore his channel, but there are a few extras in the book that I have not come across on youtube. My rating, well i kind of wish i could select 3.5 stars, because ( and I'm not sure if its just a glitch) I feel that at certain parts there are things missing, almost like your left hanging, because you were waiting for one last detail or instruction to be conveyed and it just never happens. I would recommend getting the actual book, i feel at the very least I'm potentially missing some pictures from the ibooks version. Comes down to how much your willing to pay for a few extra things that aren't on youtube and/or may potentially be missing from the ibooks.
