Colour challenge take two

I thought I would have another go at this week's colour challenge. Here is my card:I've stayed with basic black, basic gray and whisper white (I love basic gray). I've used the stamp set Together Forever along with the matching roller Forever Flowers. I used basic gray textured cardstock for the base of the card. I then mounted white onto black onto the gray. I used basic gray ink for the roller across the middle and mounted it on basic gray textured cardstock and then onto the card. I used the scallop punch on black cardstock with the 1 3/8" circle punch in gray and punched out the image using the 1 1/4" circle punch. I cut out the smaller flower and mounted it using a dimensional onto the bigger flower with a silver brad in the centre. The scallop is mounted on the card using dimensionals. I used the basic gray taffeta ribbon which I love across the middle. Here is a close up of the flower on the scallop:
