Yeah I'd say, from watching the video, that your turning-over motion seems a little slow, which might be making gravity work against you a bit. Not sure, but maybe if your turnover was a tiny bit quicker and more fluid? The video isn't a great way to judge, though. If you want to downgrade the difficulty a little, it's much easier to do this without the initial pushover. The pushover, I've found, is the difficult part. Edit: After paying closer attention to the way I do my turnovers, I realized that I don't let the cards fall on the deck: I catch them between my left thumb and index+ring fingers, and angle up for display. So that allows for instant squaring up, which means I don't have to worry about separation, but it means my technical advice on your turnover isn't helpful. As a bigger picture comment, if you're relatively new to this, I might suggest considering whether it's more important to you to master the absolutely perfect double turnover, or whether it's more important to get a "pretty good" (but slightly less technically difficult) turnover that allows you to move forward with your performances, and keep working on the 100%-perfect, falling-back-on-the-deck turnover in the meantime.
