David, Very nice project, sounds like you've been busy a few nights, Finally it paid off! tank looks great, this will be a good time to determine what to bring in this new tank from the nano and what not to bring.
From experience those toadstools grow even bigger and eventually you will have the same issue in your new tank, also, the green star polyps should be segregated in a small island in the sand otherwise it will take over the entire rock formation and it will kill and/or cover any coral in it way.
Good luck
