Why are you gutting the left side, it looked good! Can we see some more full tank/progress shots for what you're working on? Nice discus btw, I love the pigeon bloods.
I borrowed a few of your ideas for a 65 gallon tank I'm working on at the moment (that probably won't be finished until summer seeing as how I'm heading back to school tomorrow morning), that I'll be posting as an advanced-vivarium "how to" like my old 75 was, I hope it does yours justice
