Dexter, your 'scape looks great, and is one of the best ones I have seen on this thread. I noticed that the rock on the left side of the tank has a vertical side closest to the glass. This will limit the amount of corals you can put on that side, and may cause the tank to look a little unbalanced once corals start growing in. I wonder if you could roll the rock, so the flat side is on the bottom? You may need to add another piece of rock to maintain the height of the structure, which is part of what makes it look so unique. Hope this helps.
