Thanks for the feedback everyone! I do agree about the grand rock looking more robust with less substrate in front of it. The rock in front of it is also a little different, lending a bit more view of the grand rock.
Regarding stone count, there is 11. On the right side there is a small one that I placed next to the long on, it's hard to tell in the pictures but there is about a 1/2" gap at the right end of the long one and the tiny one to the right of it. I did it to create a fractured yet uniformed look to that rock. I'll take a better pic after I plant it. (another day or so).
