Just started working on my second edition of the book Fairchild published for me in 2009. This drawing will have gray shades added, so you can see the difference a little gray scale can do for your otherwise flat drawings.
The book is available now (1st edition) via Amazon
I will be working on adding more drawings and ideas for the book in the next couple of months. Would love feed back on content if you have the book.
Let me know what else you might like to see in it.
