As mentioned, take an extra second or two once you pick up the ball as it will help you set up and keep your balance better. I also second what was mentioned about your wrist. The concern I would have with having the big angle on it is that it can lead to ligament or tendon strain (tendonitis) eventually. It's definitely something you would not want to experience with bowling regularly. There are a lot of ways that you can still get a good rev rate while relaxing or cutting down the wrist angle.
On the positive- you seem to get out of the ball well and there is no doubt you can get some revs on it. That can help on the long patterns where you need to create some room for the later blocks.
One last thing: if those are house shoes, definitely invest in a good pair of Dexter or 3G shoes. You'll get a better fit and it can help with the slide by giving you interchangeable heels/soles. I would stay away from Etonic at this point since there have been some manufacturing issues causing them to fall apart quicker. At least that's according to the pro shop I go to that stopped selling them lately.
I hope you put some more videos up so we can see any changes you decide to make or any progress from time to time.
