Okay, I noticed several of the pin holes were uneven which caused the ball to "jiggle" in weird directions just before it got to the hole, so I smoothed out all the pin locations. Sorry, my bad, I should have caught that the first time.
I added a hazard spline along the right side of #4 fairway, so if you hit it in the gully, you can either play it there with no penalty, or chose a better drop with a penalty. (helps if you get stuck behind a bush)
I added a few more rocks around the #18 green and a few butterflies here and there. Thanks!
