I'm probably going to retcon this whole 'moon crown and halo' thing for the Lumerians. It was what I could draw at the time, but it's not the best idea I've had to visualize their magical connection to Luna.
"Every Lumerian has some connection to a part Luna's magic. Some have strange prophetic visions in their sleep, some can walk the realm of dreams, and some have a combination of both."
