My thoughts... first, being from Minnesota, the Garnett jersey stings a bit.
As far as your bowling... I see strength, pretty good timing, strong release, and an overall natural ability, especially for someone that's only been bowling for a year.
Playing that line, with that speed, with a urethane Natural... I would have to guess that the lanes your bowling on are quite dry. Is that normal for those lanes? Do you always bowl there? What happens when you bowl on oily lanes? Do you have a reactive ball?
Yeah, you're a little bent over, but I don't see that as a problem. There are many very good bowlers who start out that way, and many others who are upright. As Norm Duke stated in his training video, he starts both ways, depending whether he wants to really hook it, or not. The open shoulder is fine, you close it up right on time, and come through the ball pretty well. If I were your coach, I would like to see a little more knee bend, you're a little stiff legged at the line. I would also suggest that you tone down the aggressiveness just enough to smooth it out some, so that you are solid, and on balance at the line. Your slide foot is squirreling all over the place.
So, how is your game? Always in the pocket? Leave a lot of ten pins? Accurate? Spare shooting? Does your knee ever get sore? What would you like to improve?
From what I see in a few seconds of video, you have a ton of potential.
