That's looking pretty good 👍
A couple of suggestions:
1) I think your arms are doing the wrong things: your back (coffee cup) arm is going up instead of passing the coffee through the turn, while your front arm is blocking your twist instead of you lifting the elbow and putting it into your back pocket.
2) it looks like you're rushing the turns, trying to use your body to force the board to turn, this, combined with the arms, tends to put you on your back foot which is why you fall at the end.
Slow things down and you may find it easier 🙂

Hope you're still going to be OK for the coming week?
