Looks very nice.
What I always notice in videos where multirotor video platforms are involved is that every other form of video (not from the sky) is completely ignored. Given, on a golf course it makes sense to get almost all shots from the air, but I think you could have used some nice pan shots from inside the clubhouse for example, giving the whole video a nice touch from a second perspective, in this case from the ground.
Nice editing though and congratulations on your first commercial success
