Looking good, just be prepared for those corals to take over your rock work, they all usually do very well and spread easily. My opinion they look great, others may tell you that they are weeds lol.
rock work looks good, but like mentioned them so called weeds will take over your rocks. and its hard to get rid of it. try putting them on small rocks so you can control it or remove it. especially that green star polyp.
I like it. Try an Acan colony on the sandbed. They grow great, are fun to watch and to feed. Also, you can find them in almost any color imaginable, to really add some diverse color to your tank. I like the rockwork too! Great job. A few more corals may be nice, then you can work on growing them all out.
