personaly, I would go with bigger piles (and caves) at the ends, with a medium pile in the middle (to provide a sight break)
I'm also not a fan on how stacked the rocks look. it does look built rather than a pile of rocks.
before you add anything to the water, measure both the pH, GH and KH in both your tank and from the tap. the fact is with all that crushed coral in there you probably wont need to counteract the driftwood.
one thing I note, no equipment in the tank, mow are you heating and filtering this thing. its worth putting them in now and working with the aquascape to hide them, rather than trying to fit them in afterwards
