I've just be alerted by Hugo Bravo of this Kickstarter campaign for the Vision Illustrated artbook. This artbook features the process of selected artists by showing you the drafts, iterations and final artwork. Below are some page previews.
Nicolás Uribe has launched a Kickstarter campaign for his artbook called Painter. He's a very accomplished painter especially for portraiture. The artbook will feature his paintings as well as instructions about his process.
The ABC Double D's of Burlesque is an illustrated encyclopedia about the art of striptease. I won't have imagine there's such a book if I wasn't informed by one if its co-authors Bashar Sawalha (the other's April O'Peel). I thought the drawings are pretty good.
The Art of Tom Bancroft, Vol. 1 is up on Kickstarter. Tom Bancroft is an artist who has worked on many Disney animated films, is a tutor and has also written several art books.
It's great to see that he's coming up with and artbook. The Kickstarter campaign's goal has already been reached so if you want the book, back for one before the deadline 21 May 2016 at https://kck.st/1Sx09sV
