QP Challenge Quilt

I finally started putting my "I Must Be Off My Bobbin!" Quilt Challenge together.  I decided to use orange.  A lot of orange.  The name of this quilt might be "Orange you glad you like orange?"  I'm liking that I have wide open spaces for quilting - I like that a lot!  But I'm thinking that a little diamond in the middle of the orange area would be kinda classy.  What do you think?  My final choices for the diamond are the black and the gray.  I'm leaning towards the gray.

 Black, purple and teal diamonds.  Like the black (upper left) the best of these 3.

 No diamonds.  Like this version too.

Black diamond and gray diamonds.  Liking the gray, but also like the black.  Although the black really draws attention to itself. Arrrgh.  Decisions, decisions.
