it nice, i may suggest something, make sure you have enought room between your rock and glass for your magfloat or watever you use to clean glass (front and side pannel). some rocks seems pretty close to the glass preventing a good an easy cleaning.
i would also be tempted to push your squape deeper in your tank, it seems in the middle of the tank, if it's intented, ok. but ifeel you may want more room in front for corals,
just my 2cents,
nice work so far
