The Moon is a Major Arcana card which can represent dreams and delusions, an uncertain or fearful future, and a need to overcome harmful negative emotions (among other things; this isn't a place for a comprehensive lesson).
I've been in a Sailor Moon mood lately, and wanted to do something with Usagi/Bunny. A reversed Moon also means anxiousness about the future, but unlike when upright, the path you see ahead tends to be one you should follow. The dreams here aren't delusional. You need to have faith and confidence that you can make it through, no matter what fears or past experiences hold you back. Princess Serenity's dreams took her to Earth with Endymion, no matter what the cost.
Also, I got to draw a crescent Earth, and that was really fun.
