I'm going to begin by tucking in the first unopened bud in between the eucalyptus seeds.
One of the reasons I chose the eucalyptus because of the soft melding of colors with the tropical protea.
I place a more opened bloom in towards the center.
Cluster the blooms tightly. Covering up the mechanics (in this case the bouquet holder) is always the first rule in good floral designing.
Pay attention to how you face your flower heads. Center blooms face straight out, and as you move out to the sides your begin turning the face of your flowers outward.
See how the flower faces are placed in reference to the center.
You can add in more seeded eucalyptus if needed.
