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.
