Jetski, my view is this. As it is, i think your scaping is too close, whereby there's not much space in between rocks. This i feel is not so ideal for fishes, especially since you seems to like big fishes as they need some space to swim through and hide/sleep. Hence, I still think creating a couple of caves/crevices for fishes to swim through will be better.
I also suggest you increase the height as now, you have plenty of space up top. I doubt your SPS will grew so fast till it rest the top. If it does, likelihood is you will already frag it as it will be way too big If you wish, can put some fast growing SPS like birdnest etc on top.
