The colors that I don't like in the finish are the blue and the black/gold print. I think that instead of just doing strips for 19 inches you might have a better balanced quilt by adding narrow strip(s) then a sashing made up of some sort of block or fyling geese of the remaing colors and finishing with borders and ending with a binding of either black or the maroon or whatever that rose color is. Your blocks are so stunning you don't want to lose them in a large field.
