I feel the shelf on the left is almost too high. I see people constantly build rock to near the top of the tank. Corals grow, 4-8 inches of clearance seems like you would have a hotspot very few corals could grow in. Most sps need 250-350 par, mid tank should be fine for most if not all. Give corals room to grow !love the look.
i'd go higher.
add another shelf.
