Not much, really, since that was your first time. Just keep doing them. It looks like you did a set up turn. Make more pronounced. You wind up at the last second and snap as you are coming off the lip with the right timing. Make your wind up a bit more deliberate. The amount and timing is right though. Pop off the jump a little bit more and this will help to bring up the board to you so you can grab, eventually.
If you increase the amount of set up turn slightly and wind and snap a little smoother and deliberately, you'll find that you can rotate more with your whole body rather than mostly your shoulders as you are doing now. That, combined with the more authority in your pop will make your spins floatier and smoother looking. The good thing is that you are relatively quiet in the air and aren't hucking it. Just try to increase it all slowly a little bit at a time, and honestly, a lot of it will come naturally from just doing it over and over again.
