To me drawing is an active pursuit, but basic instruction is helpful. This book provides plenty of that; however, my main complaint is the lack of actual drawing or pictures for us learners to visualize. It's narrative heavy.
This is a fairly comprehesive text on the rudiments of sketch, shadow, planning, perspective and so forth. There are pictures throughout, but they are not high quality, and, in general, I didn't find them very useful.
I would have prefered to see a series of progressive shots, perhaps breaking down a drawing, working through the craft with a more step by step detail and the art work to go with it. Maybe it's just me, I can't just read about something and then start doing it, I need to be shown- take me by the hand, start me slow, move me along, give me something to look back at and compare- like that Norman Rockwell painting(in fun on their cover) where he's staring at himself in the mirror seeing if he's got it right.
I don't want to totally bash this book because it does offer helpful info; it simply doesn't appeal to my learning ways- it's more of textbook vs. the typical Dummie's self-taught guide.
