Beautiful quilt! Love the choices of prints. The quilting is all a personal choice, but I will give you my two cents worth! I would do a basic SITD around the big "stars", a very simple design inside the stars (I think that the print of the big stars won't show nicely with a busy design), and a busier design in the "snowballs" if you want. This is all just my honest opinion - most quilters like much more quilting than I do - I want the fabric and block designs to show.
