that seems to me the absolute key, ie features (and micro topographies) that neither help nor hurt a golfer's path to the hole, and so help foster a pleasing sense of naturalistic randomness, as if the course (like St Andrews Old) has been there for 150+ years -- the architecture & design evolving over time and conforming itself to the features, instead of the other way around. I've come across that quality exactly never in real life golf courses I've played, and only rarely in photographs of golf courses I've seen here on this site. It seems remarkable to me that Tom's team has developed the skill to recreate that quality/essence so very well, on the ground -- even with the wonderful level of detail your computer work provided.
