Nice work on advancing your 14.1 game in a short period of time. Also, thanks for sharing your video... it's always hard to put yourself out there for people to see but it almost always inspires others to do the same.
I also agree that you will be running in the twenties in a very short time. I am also a nobody, but just a couple of tips to help you get there. First, to work on getting shape on the break ball, start with just 4 or 5 balls on the table (place them in an easy pattern) and mentally work your way backwards from the key ball (last ball before the breakout ball) to the first ball you will pocket. Then just execute to this plan. Normally, an ideal key ball will be parallel with your break ball.
And, also, while shooting every shot, I noticed you lift your head about 2 or 3 inches just before you shoot your shots. This can potentially cause numerous stroke execution flaws. I would say just practice knowingly keeping your head in the exact same position until the cue ball stops rolling.
Keep up the good work and please keep posting your videos. I will hopefully be posting some videos soon as well (as soon as I get a good camcorder).
Again, thanks for sharing.
