One thing I've learned over the years of doing aquascape and growing coral etc. I no longer try and "build" an actual scape. I put some rock in, get the tank settled, then as I add coral I build the scape. Even if I add several pieces I continue to build it up over time. It can, quite literally, take me a year to get everything in place. And sometimes I am still moving stuff around to find the perfect position for a certain coral and keep a lovely shape to the scape. I guess what I'm trying to say is, you don't have to be DONE, you can take as much time as you want, move stuff around, stand back, *****, wait a few days then move it around again.
