Looks pretty good so for.
2 tips of advice I think would help.
1: on the beginning of each hole, have a camera start zoomed in on the ball and then zoom out to the whole level. So you know where the ball is. It took me a couple minutes to find where the ball initially was when the game started.
2: have it where you can hit the ball even if its not completely stopped. Mainly because, it takes a while for the ball to come to a complete stop.
