You are a good bowler.
Here is what I think. You are kind of inbetween
styles. Like Brian Voss and Pete Weber.
I noticed your ball had a strong mid-lane read. I
do not know your ball/drilling and lane condition.
If I were you, I would experiment with a few things
to see how they worked. First, I would put my
left should in front of my right shoulder. Then,
I would also dip my right shoulder down below my
left shoulder. More upper body tilt. Accelerate
more on the down swing. When you open up
your shoulder, make sure your two fingers fingers are on the inside, towards
your body. Maybe, make point of release a little farther past
your ankle.
This is not an exact science. Many ways to skin a cat here.
Here is a picture of PDW describing some of
the stuff I am talking about:

see how it works for you.
