As a fussy professional designer I am forever trying to improve all of my skills, and although a competent and descriptive sketcher, I thought buying this book might have some more indications as to areas I can do exercises in to improve my sketching even further; please note this is not the case, this is NOT a 'tutorials' book.
I'm a bit confused by this book, I'm not sure what it's aiming to do! It was a toss up between this book and 'Sketching: Drawing Techniques for Product Designers' (yes, I realise sketching is different to drawing). Too much text, not enough visuals which I wasn't really expecting. What was/is interesting is seeing the difference of drawing from the Italian designers (i.e. Perry King) and current American designers (Michael DiTullo). I feel the information sometimes goes way off course (i.e. describing what a computer is, what RAM is, what a hard drive is... is this really essential?) and I wonder how many pages would actually be in the book if they were to take out the seemingly useless information.
Basically, I think Pipes has missed his market, I think there is too much text which feels like 'filler', and not enough visuals to whet the appetite and make me enthusiastic and energetic about drawing/sketching.
