Love your quilt and colors.
Did you and the LA discuss what you wanted done or did you give her free choice?
If you did not discuss it with her, then you cannot blame the LA.
If you did and she did not follow your wishes, then by all means let her know.
No one can improve upon their abilities unless ther are given some constructive criticism to know where to make the changes necessary.
Personally I would have done a star within the stars and a pattern in the sashing areas.
All that said, it still looks nice because of your pattern, colors, and design.
