Training following this car...

well... the driver here is a good friend of mine. these shots are from a "professional" pilot who takes part in these competitions as drone operator. now my buddy is not very happy with pretty much everything (shots are too dark, overexposed, out of focus, don't show what he would like...). he doesn't see the point in paying money for it. so he asked if I could come with him and do it better... sure, I'll just do it better🧐... but since 95% of the time I only sit on the edge of the forest and fly through, around and into trees 😉... I told him I don't know if I can even do it Like that... it's not like you can practice drifting cars on the outskirts of town every weekend... any tips and recommendations about where and what I could practice would be helpful.
