KelliJo, I like the horizontal layout, but I would wrap ribbon around the card (toward the bottom of the image), with a simple knot on the lower left side of the image, and would add 3 of the "itty bitty blings" to the upper right side of the card. This would balance the card and add some visual interest. I love the stamp, your colors and the bling you added.
