Stability, functionality, and ability are things to consider in addition to the way it looks. Can you clean the glass all of the way around the inside of the tank? Do you plan to secure the rock work together to gain added stability? Are you planning to focus on corals, fish, or a mix? You have some great platforms to put corals and nice archways for fish to swim through, but may not be places for smaller fish to hide (may or may not be an issue). Are you planning to stay bare bottom or add sand? Good luck with this new setup - it already looks good and will look even better soon when you start adding livestock!
