Overall, your form looks good. Nice line, good posture, solid bow arm. The thing that I notice in the second video is you are collapsing slightly before release. Watch your arrow on the first shot, it slowly creeps forward after you anchor. Last shot watch your draw arm elbow. It starts in good alignment at anchor and by release it has moved into a 5 o'clock position (if you're familiar with Terry's form clock).
The solution is simple. Once you're anchored focus on pushing the bow arm forward while pulling the string hand backwards. I like to focus on pulling my draw elbow backwards and feeling the scapula pinching together. While it is important to relax during the shot it is very important to maintain a constant pull.
As an added bonus, getting rid of the creep should also help rip the string out of your fingers during the release.
From the vids you posted that's the main thing I see. Like I said, overall very good. BTW, you have a great area to shoot.
