Very nice tank!
I would move the bigger newer live rocks to the left side myself resting directly on the sand, maybe create a cave by leaning one against the other.
Then stack the rest of the rock to the right side leaving some flat areas for your corals to rest on, but it's your tank so if this is the way you want it to look that's awesome, I find with myself i'm never happy with my aquascaping.
I'll be honest I didn't like your first few pictures you started this thread with, the tank was very dirty with no live rock but now it looks great.
I'd stop buying fish until your tank settles in for a month, I did the same thing myself before. I moved from my parents house to my own house and cleaning adding new live rock and moving really unsettled my tank.
