Hi Lynn, looks good-- take a look at the rock work from the side. We tend to set it up in a straight line... making it zip zag a little or creating sort of a cove should help break it up a little. You will enjoy viewing your tank from the side, and breaking the rock work up visually will help.
Also I like to focus on having as little rock touch the sand as I can (and still be stable). This allows flow and light reflection beneath the rock. The light reflection keeps the tank from looking dark over time. Also look at the height of your rock work.... considering whether you will add coral one day and the types, think of how much height you want in your rockwork. Use pieces of rubble to stabilize also ... you can putty them in later. And only putty to stabilize.... too much makes the rockwork too permanent.
