Wellcome,
I'm a newbie as you but I follow a lot of stunters on youtube such us "RedKeyMon", "Dada9x9", "FishyDizzle", "Escozoo", "Oh Brox", "mafiastunting", , "Yellok", and "Asho1"... and some "stunt crews" such us "Evolve Stunting" and "Cryptic Stunting". Also "Nomad Union" and "Versa Alliance", but they are very inactive.
What I do is review over and over again the clips on their channel, so I can study how stunt works, and that's how I learn to stunt. Also find some tutorials on youtube, but the most of the time I just watch the videos and try the same stunts they have done. When a new video comes out, try to analyze the way the stunter makes it. Download it if you can and play it in slow motion, pause, take notes... and then, go to the game and experiment. Spend as hours as you want, and take stunting as a game ^^
It is a really complex way to play. It requires patience, persistence, skill and A LOT OF time (at least for me... but you know, I'm a newbie he he). By the way, I play PS4.
So, have a nice stay here ^^
