Golf
The first title for this book was The WORLD of GOLF.
That type, encircling the world was my first step.
The publisher sent me a giant coffee-table book on golf courses,
so I could intelligently design and draw a golf course.
Custom brushes came in handy here to allow me to
control focus and depth-of-field of the foreground grass,
which could be challenging to get right in a close-up photo.
