I always think there's room for improvement.
I believe that is the curse of Golf as well, you could have hit that little ball just a little bit better.
Truthfully we are all our own worst critics, and always searching for a better finish.
That is the advantage of a forum like this, it shows your work off and enables a true appreciation or critique to be offered, and I'll offer the finish is excellent also the bowl is well turned and a good shape.
