The OBs really seem to like you. Bounced your CB back on path a couple of times and sat almost Kosmo style.
Yeah, that's bound to happen sometimes with 15 balls on the table that you have to run in order. He seemed to have less of a problem with that as the run progressed. As a certain very famous rotation player might say, "He got lucky."
Seems you are getting some excellent comments here. As far as the fast flutter strokes, I see a lot of top players doing that. Maybe to relax the hand and get the jitters out? Dunno. Stance seems a bit unorthodox, but it works for you, so...? Seen Shaw make a lot of shots like that rather than reaching for the rake. I noticed that you are cross-dominant and have the cue under your left eye. Shaw is a southpaw and has his cue under his right eye. Something to think about.
I also am of the opinion that you may be deliberately staying down longer than you need to. Your style reminds me of a horse that is being held back by the reins. Try letting go sometimes and letting your natural rhythm out.
One thing that wasn't mentioned is that you have quite a large gap between CB and tip at address. Not saying that's bad at all, just that there was a recent thread where many good players here said you should get as close to the CB as possible without fouling if you want to hit the CB where you intend to. Not saying I agree with that notion, just that nobody mentioned it yet.
All in all, some very nice shooting.
