Hey I was already learning it before the tutorial by deconstructing the instagram video so I got some experience with it and with all the mistakes.
So the video didn't really change much for me though I think the tutorial shows everything but it just takes a LOT of tries to figure the rest out and those are things that would have been hard to explain anyways. + I think that putting in that extra effort yourself because he didn't provide audio information will only help you learn to perform it better.
The last 2 days I've picked up my efforts on it again and I'm almost there now myself.
The only thing I mess up now is the catch haha which seems to be the hardest part for me, I can catch them but it just doesn't look as clean yet, but even his catch is not that clean imo.
I'm close to being able to record it, and maybe you can do the same.. I'm sure I can spot the problem now as I've finally figured it all out.
It's hard to say from your post what you don't understand or what you are doing. So I will need to see you perform it to help you out. And I don't care if it's sloppy af
Or that the cards just completely drop out of your hands. Preferably you let someone else takes pictures or record it from a few angles and I'm sure I can help you overcome the problems with the move. That is if there are technical problems, which probably there are. Because there are a few OOOH like that moments while learning this move
I should be able to upload a video of my performance on it in a few days.
