Welcome to R2R! Can't wait to see this build, do make sure to start an official build thread when you get started.
I'll +1 to keeping the rocks off the glass on all sides if possible. Makes access for cleaning much easier and keeps from having dead spots. And with a peninsula tank, 3-sides of viewing is a given Mine is not a peninsula tank, but I still prefer not to have my rocks touching the glass...
I really love this minimalist look, but maybe with just a *bit* more rock and caves for fish.
