Great Idea and true statement probably in the life of a bird and a fat 9. However the term Blue Moon corresponds to the third full moon in a quarter of the year when there were four full moons (normally a quarter year has three full moons). Full moon names are given to each moon in a season: For example, the first moon of summer is called the early summer moon, the second is called the midsummer moon, and the last is called the late summer moon. When a season has four moons the third is called the blue moon so that the last can continue to be called the late moon. They occur every 2-3 years.
I like everything quite a lot except for all the black up top. Try it cropping off the top so the moon is centered vertically, so it's a long horizontal image, and see what you think.
