I am simple to the extreme so bare that in mind!
I LOVE the background you did on this card...I think it's great and has lots of detail. Because of that, I think instead of a cutout flower in blue (and crystal laquer?) ... I would go with it just stamped, sponge if necessary to fill up the white space, colored lightly to match the background color and blue...and then mat that image with a small layer of the blue. That way you can include the phrase right there with the flower vase.
