When you use two colors in Hunter's Star the quilting becomes even more critical as the stars tend to fade into the more dominant color. If you are going to have this done on a long arm machine, I found a pattern that emphasizes the points of the star and while it did not quite outline the points it did have a pointed geometry and helped defined the unit as an eight pointed star. Because I used three colors I did another geometric shape to fill the star's indentations and then third more dense design to fill the large triangles that formed the large squared background. However, in this case I would choose a rather bland and somewhat densely packed design for the entire background and that should help make the stars "pop" even more. The last thing I might suggest in using a puffy batting. The loft of the batting made the stars even more prominent.
This is not an easy pattern to sew and it looks as though you did a great job in the piecing, so take your time deciding on how to quilt it. What you and others feel is too busy now, can be tastefully "tamed" with the right quilting and ultimately a joy to own.
