Learning how to cluster objects is important. We have all seen cluster in previews of kit, or quick pages. The point is to draw the eye in. Generally your cluster will look better in odd numbers. Important to remember that things don't have to be used as intended. The stem laying in a horizontal manner appears now as a ribbon or border. Add the one berry sprig and it starts changing the look immediately, although a few well placed would have added balance. If adding a few flowers (below left), makes the layout seem more feminine than excluding them, more masculine (below right).
