it looks pretty cool, one thing though... don't feel obliged to use every rock that came with your purchase. Choose the ones you like best, and the ones that go together in a lock and key fashion. The best aqua-scapes i've seen are those that appear to be one large rock, avoiding the stacked rocks look. Also, keep in mind the type of coral you plan on keeping and the growth patterns of each coral. Keeping tall pillar type structures tend to lead to shadowing by the corals up top, particularly with sps. Good luck and don't rest until you find something that completely satisfies you.
