You need to be more patient with your arms. I would suggest that rather than simply bouncing out of the hang position, you set it momentarily, then start the lift smoothly with a push of the legs. The way you're doing it can certainly be done well, but it makes it far more difficult to be balanced, to create tension properly, to keep the bar in, and to keep the arms relaxed.
Relax your arms - let the weight of the bar stretch them long. Engage only your back and shoulders to actively push the bar back into your hips as you extend. The first movement should be a push of the legs, then a snap of the hips with a continued push of the legs. The arms need to remain long and relaxed, and your lats engaged to push the bar back, until this extension is complete. That will not only get a lot more speed on the bar, but will allow you to keep it in against your body much better.
Once that extension is done, then keep pushing the bar back toward yourself and pull the elbows up as high as you can and to the sides before turning the bar over. Think of squatting with a vertical trunk rather than sitting back w the hips as you pull down. You won't be vertical, but it will help keep you from leaning into the bar and moving away from it.
All that said, I'd say overall you're doing quite well.
