The Artists of Marvel Studios Visual Development: Ryan Meinerding, Charlie Wen, Andy Park, Phil Saunders, Jackson Sze, Rodney Fuentebella, Anthony Francisco, Karla Ortiz and Adi Granov provide the text and artwork for this instruction book.
These artists describe the Marvel Visual Development team's approach to character design and rendering, followed by 20 step-by-step discussions of character development/design/rendering by the individual artists.
However, do not buy this book for digital painting tips, the focus is on the mental aspects and their thought process.
The book at 7.5 x 11 is smaller than one would expect, the illustrations are very small--uncredited and uncaptioned, and the paperstock is very thin, but the value in this book is in the text--the artist's thought process--if that excites you, you won't be disappointed by this book.
