*More 3d and building work (and a pool which still needs some work with tiles, fence, planars)
*Few textures modified
*Some ponds and irrigation ditches though mostly those are not in play.
*Some tees moved to give more interesting teeoffs
*New plantings
*Redone greens, some enlarged and different pin placements on some of them
*Bunker work, few extra ones, and reshaping of others
Quite a few other things that I don't remember right now.

Overall, I wouldn't say it plays any harder. Maybe easier in fact. But this is just something I did for my own personal satisfaction. But of course I hope people enjoy playing it. Anyway, a few screenshots of the course, with a few taken from spots you probably won't find yourself in during a normal round.
Cheers, AJ
