IF IT WERE ME.... I would remove the flat rock on the right side. There’s already a table there. I would also remove some of the smaller rocks on the sand bed and the left side.
If it is just going to be a fowlr, I would make a bridge in the middle with that smaller flat rock and take all the knobby bleached coral heads and use them on the top of the rock work on the right and left creating two high spots. I would also get some epoxy/glue to aid in stacking the rock work higher.
