My 2 cents (all it's worth :smile: ):
You have a nice smooth stroke- seems like good fundamentals from what can be seen in this video. However, you need to watch something. You tend to move during your break shots. In the first break shot, your head starts up before you have even contacted the cue ball. Your head does not do this on any other shot, so you might want to figure that out. On the second break shot (your last ball pocketed) you almost move your head up again, but do move it a little as you are stroking the shot. I might not have noticed it if I hadn't seen the more definitive example in your first break shot. Sometimes on a break shot when you are hitting harder your arm gets in the way of your body as it follows through, and you can tend to move the head up. It's not something you to badly, but something to be aware of.
At about 4:30 you attempt a 2 rail position shot that I'm guessing did not go as planned. Where were you trying to get the cue ball, and why do you think it didn't go there? You absolutely have to know where the cue ball is going after it comes off that first rail. You recovered well, but missing your position often ends a run, as I'm sure you know.
Any way to get a higher vantage point on a different table somewhere?
