Looks really good so far. One suggestion I would make is adding a mount to the far left structure. With such a narrow base it may get knocked over fairly easy. Also what did you use to secure them together? Also what types of corals and fish are you planning on keeping? You want plenty of places for your fish to hide, as well as spots to mount corals on. Also you need to consider coral growth and how frequently you will need to prune to keep them from causing issues with each other.
I used emarco 400 cement, epoxy putty, super glue gel, wire ties and fiberglass rod.
Corals SPS, LPS, zoas and mushrooms. Fish who knows lol.
