First off, it looks awesome!

My biggest concern would be if you ever got something in the tank that would move the sand around some, the rods will be exposed. This would cause a big eye sore. My engineer goby's would have them exposed in about half an hour. If you aren't considering ever getting something that may do this, then it isn't a big deal.

The other issue I could see with perchering the rocks up on pegs would be anemones. They may get underneath the rock and shift it around. They may even topple the rock on themselves. While it would be difficult to do, I've found anemones that live in the sand extremely powerful. If you aren't looking at this type of creature though, you have nothing to worry about.
