Trying to progress to cutbacks

First of all, thanks again to all who volunteered their advice. I feel like I've made a lot of progress over the past year. And maybe I'm again in uncharted territory.
I feel the ride below could have been extended a bit had I managed to do a more aggressive top turn, back towards the breaking part of the wave, which I guess is what they call a cut-back.
It's happened to me a few times, on the Bic and my shortboard, that when I attempt that I fall off the board, like back in the day when I was trying to bottom-turn.
The shore camera feed cuts off before the critical part at the end so I did not include it.
Any feedback welcome!
